I have noticed the trend to discard the assumption that Holloway was Alsey McGinnis Pass' maiden name. I can't prove that William McGinnis who died in Halifax County, Virginia in 1760 was Alsey's father, but there is a strong thread of circumstantial evidence that he was:
1) In 1762 Isham East sued Nathaniel Pass and Robert Wooding, administrator of William McGinnis deceased, for breach of promise.
2) in 1764 his son William sold 131 acres (including "the part wheron sd Wm the elder lately lived") to Nathaniel Pass for only 20 pounds which strongly suggests a brother-in-law deal.
3) When Nathaniel sold the land for 100 pounds in 1776 his wife Allice and Elizabeth McGinnis relinquished their rights of dower. Elizabeth was the widow of William McGinnis and she had not waived her right of dower when the land was sold to Nathaniel in 1764 which strongly suggests that she lived with Nathaniel and Alsey after William died.
4) William had a son named James and in 1795 a James McGinnis sold land in Caswell County, North Carolina which joined Nathaniel Pass.
I would be happy to have your thoughts on this subject.
