About William Whitham
William Whitham (spelled Wittam) married Elizabeth Smith at St. Stephens Church (by the Rev. Richard Sewell) January 31, 1722, in Cecil County, Maryland. I am descended from their son William, baptized in April 1725, again at St. Stephens.
A lot of work has been done on this line, and a nice overview is at Jane Topoly's site (http://bit.ly/2P0X0V). There are records of earlier and contemporary Whithams in Cecil County and nearby Kent County, Delaware, that are in all likelihood related. Many were associated with Bohemia Manor and its owner, Augustine Herman, of Sassafras Neck in Cecil County.
An earlier Whitham (Witham, Wittam, Whittom, Witton, etc.) family appears in Maryland, beginning with the 1651 arrival of "John Witham," who arrives along the Patuxent River in what later becomes St. George's County, Maryland. "John Withan," probably the same man, is granted "Phillip's Land" in St. Mary's County in 1652 (Cert #100, Liber AB&H, Folio 301).
There is no proven link between this St. Mary's County Whitham(Witham)s and those in Cecil County, although there is some circumstantial indication that the families may be connceted. What is singular about this Whitham family is that they were closely connected to the Catholic Church in Maryland, particularly the Jesuits, which may be a significant clue to their English origins. There was a noted Catholic Whitham (Witham) family in Yorkshire, centered around Cliffe Hall in Manfield, which provided leaders to the church for more then two hundred years.
