About Jane Calvert

--- In, "James" <j.calvert@...> wrote:

It is true that We do not have proof positive that John Calvert of Mifflin County married Jane Swayne Mercer. However, there is sufficient circumstantial evidence to arrive at that conclusion.

At the moment, there is speculation bordering on certitude that John's wife was Jane Swayne. Jane was first married to Joseph Mercer and, after Joseph Mercer's death, married John. The date of marriage between John and Jane is given as 1764.


Jane definitely married a John Calvert after her marriage to Joseph Mercer. She is listed as Jane Calvert in her father's will. John Calvert became the guardian of Jane's children by Joseph Mercer. Mr. James Ray has found the documents attesting to these facts in the records of the Orphan's Court of Chester County, PA. In those records the court refers to John as Jane's husband; (See Chester County PA Orphan's Court, March 21, 1769.)

Strong circumstantial evidence and a shred of court documentation indicates that John Calvert of Mifflin County is same individual who is indentified as the husband of Jane Swayne Mercer Calvert.

Research at the Cumberland County Historical Society has revealed that a John Calvert and his wife Jane were deposed before the criminal court in 1779 (See Schaumann, Merri Lou Scribner, ndictments-1750-1800-Cumberland County, Pennsylvania, 1779, item 808).

John Calvert, according to tax records of Rye township was a resident of that township as early as 1774. John Calvert, blacksmith of Rye township, granted a moeity on 200 acres in Cumberland County to Alexander Power and and John Ordd of Philadelphia March 27, 1774. James Ray found other evidence that John was a blacksmith. He probably worked in one of the forges in the area that later became Spring township of Centre County. Tax records indicate his presence there up until 1796.

According to the Pennsylvania Archives, Amos Mercer and John Calvert , Sr., were both in the Cumberland Militia, Fourth Battalion, in 1777, under Colonel James Wilson. John is listed as John Calver. John Calvert was in Class 1 and Amos was in Class 2. (Pennsylvania Archives, Series 5, Volume VI: Muster Rolls Relating to the Associators and Militia of the County of Cumberland for 1777.) pages; 244, 245 (John is also listed on the rolls of 1778.)

Amos Mercer, Jane's son by Joseph Mercer, is shown as living in Potter Township of Mifflin County, PA, near John Calvert, Jr. (who we believe is one of Amos' half brothers) in the 1790 Federal Census. John Calvert, Jr. was married to Esther (Hetty) Jones. All but one of their children were born in this area.

In the same census, John Calvert, the elder, lived in Upper Bald Eagle Township of Mifflin County which was only a short distance from Amos and John, Jr. The record was muddy in later census.

John Calvert, Sr., is believed to have died in 1796.

In the Federal Census of 1800 there is a "--------" (possibly Widow) Calfert shown on the census living in Upper Bald Eagle Township of Mifflin County. When this area became a part of Centre County, the area became Springs Township of Centre County. In the 1810 Federal Census, a Jane Cabert is found living in the area that was formerly Upper Bald Eagle Township.

We puzzled over the years between 1796 and 1810 for a long time. We could not find the burial information for John or Jane. We still cannot. But, more puzzling was our inability to find Amos Mercer or the Calvert boys during that period. Daphne Toomey found Job Calvert, second son of John, in Crawford County, in the 1810 Federal Census, but we were unable to locate John, Jr. or Jacob. Amos Mercer surfaced in Vernango (Armstrong) County, PA in the 1810 Federal Census--where he settled and died. This did not make sense if he was a relative of the Calvert boys. They moved to Belmont County, OH at some time before 1830. Jacob, his third half brother, was believed to have been in Belmont County as early as 1805.

The break through on the latter came when we learned that the wife of Job Calvert was Chloe Benn. According to the history of Crawford County published in the 1800s, (Bates, Samuel P., et,al., History of Crawford County, PA; Warner Brothers, Chicago, 1885) Jonathan Benn, a renowned early Methodist preacher and brother-in-law of Job Calvert stayed temporarily on Job's farm and then moved to an adjacent township. Amos Messer (Mercer) was also in this same township with Jonathan Benn for a very short time, but moved on to Vernango County. The land Job Calvert purchased in Crawford County was sold to him by the Holland Land Company. The same company was selling tracts of land in Vernango County as well. (I am trying to see if I can find the document of sale in Vernango County to Amos Mercer.) It would seem Amos did move with at least one of the Calvert brothers.

Job would probably have remained in Crawford County for the remainder of his life. He was well established there. Instead, he pulled up roots and moved on to Belmont County, OH, where his brothers now lived. This is where he and Chloe are buried. Family tradition states that Chloe went insane over the inability to have children. The Benn family states that Job and Chloe had two boys in Crawford County, Robert and Isaac. There is no indication that these boys moved to Ohio. A disaster involving those boys would make more sense for Chloe's insanity and Job's decision to move on.

Amos had no reason to join the Calvert boys in Belmont County. He was well placed in Vernango and his children bought farms nearby.

Mrs. Rena Brown and Mrs. Carolyn Joy informed me early in my research that John Calvert, Jr. and his wife, Esther, passed on a family tradition that they moved from Centre County, PA, to Belmont County with the Mercers. We do not know which Mercers. There were a number of Mercer families in Belmont County during the 1830 Federal census. It is possible that the tradition referred to a movement to Crawford County. Or, a relative of Amos Mercer might have moved to Belmont County and then moved on before being enumerated in the census. Edward, Amos' son, died in Indiana according to one source.

In addition, John and Esther named one of their children Hannah Mercer Calvert. Hannah Mercer was the sister of Amos. (We did not rely too heavily on this, early on, because it could have been a thing of a family naming a child after a close friend. Now, it seems to have much more significance.)

Rena and Carolyn's information led us to seek the assistance of Mr. Justin Kirk Houser, current moderator of PACentre@... to establish the parentage of John, Job and Jacob Calvert. We found strong evidence that their father was a John Calvert who had resided in an area of Mifflin County even before that county was formed that was later transferred into the new Centre County, PA. But, records were few.

The advent of the Calvert Family DNA testing, coordinated by Mr. David Bell, has thrown new light on who our ancestors are. Our particular family's DNA does not match any other branch of the known Calvert lineages. It does match a particular lineage of people by the name of Calvert who came into PA from Ireland in the great Quaker migration. We have enough people of diverse segements of this lineage who can document their lineages back to this group to say that it is the same family. Our DNA matches theirs. We can, through the work of others before us, trace it back to John Calvert of Armagh, Ireland and probably into Yorkshire, England. This part is a certainty. How segments of this line relate is still a matter of conjecture and await documentation.

We are not, as so many of our relatives and ancestors believed, related to the Lords of Baltimore or any other Calvert family of whom we know.
