Ann, Still don't know who Margaret's parents were or my William.We know Jackson Harrison was living next door to William 1850 Census. He did name one of his daughters Margaret. I don't really even know if Jackson is a brother to William, but feel that it is likely.When I find out Williams father I will let you know.I notice you are doing Burgess research, is that on the Allday side? Harrisons married into Burgess family.That Could be your Harrison connection.What are some of the other surnames.Sibling to John Alday,Who did they marry? Any Jacksons, Moores, Colemans?
