(from http://files.usgwarchives.net/pa/bucks/history/local/davis/davis08.txt): Henry Marjorum (present form Margerum) and wife Elizabeth, county Wilt, England, arrived in the Delaware, 1 mo. 2, 1682, and settled on a 350-acre tract two miles below Yardley. He then bought 281, acres in Falls. They had two children, Sarah born 7, 17, 1685, and Henry born 12, 7, 1683. On the death of his wife, 8, 2, 1693, he married Jane Riggs, a widow, the first marriage in Burlington outside the meeting; we do not know when he died, but his will was recorded 1727. The name of Henry Marjorum appears as the owner of cattle, 1684, and the ear mark given; and one of the same name, son or grandson, was one of the first directors of the Newtown Library, 1760. The same year, he, or another Henry, went on a "voiage" to South Carolina with a certificate from Falls Monthly Meeting; but there being no monthly meeting near where he was he "could not deliver his certificate nor get an endorsement of his behavior." In 1765 John Margerum "was much overtaken and disordered with strong drink in a public manner;" and 1766, a committee was appointed to treat with Henry Margerum, who was accused of "unlawful conversation" with a young woman. Both were dismissed from meeting because they were in "an indifferent and unconcerned" frame of mind. They needed disciplining and got it. The homestead was occupied by William Margerum, who died there October 9, 1830. His wife's name was Elizabeth, and their son, Enos, born June 30, 1782, married Rachel Vansant, whose brother John was an Ensign in the Pennsylvania Line of the Revolution. The latter had three sons. Reading, a second son, born February 18, 1811, died December 20, 1897, and Garret, born January 22, 1813, went south in his youth, led an active business life and was killed at Memphis, Tennessee, 1891. The Rev. William Allibone Margerum, Ocean Grove, N. J., a prominent Methodist Episcopal minister, is a descendant of the pioneer, and his youngest son, Winfield L., born 1861, is engaged in business in Philadelphia. Several members of the family served on the side of the colonies in the Revolution. Joseph and William in Capt. Stillwell's company, Colonel Keller's regiment, Bucks county militia. The names of Benjamin and Jonathan Margerum were on the rolls at different periods.
