I can only give you answers from my Acheson Family.
Thomas Weir Acheson b. 1811 married Katherin Leavett Hooker.
Two of their sons and a daughter had Hooker in their names: Mattie (Martha) Hooker Acheson b.1849, Thomas Hooker b. 1853 and Mortimer Hooker b. 1863.
Katherine's father was a Thomas Hart Hooker, b 1770, his father Thomas Hart Hooker Sr. married a Sarah Whitman whose father was Deacon John Whitman, and there is more history of their connection with founding Hartford, Conn.Thomas Hart Hooker was one of the first who served in theRevolutionay war... which allows us to claim DAR status.
sorry for wandering:back to the Hookers in the Acheson line.Thomaa Weir also had a son, Harry Webster Acheson b. 1858 who had sons by two marriages. 1. to Mary Hinsdale Duval and 2. Jane Correne Reeves.From first marriage they had a son Harry Hooker b 1889 married a Minnie Trometer, who had a son Hooker Calvin b. 1913, who had a son Robert b. 1964 and David (don't have any info on David). This Hooker Calvin was in the navy and I believe is buried in Maryland. I don't know if Harry Hooker and Minnie (there are several variations of her name) had more children or not.I was once in contact with the Robert b 1964, but lost contact and don't know any more.Harry Webster's marriage to Jane Correne produced a son, Mackall Webster, who named one of his sons Harry Hooker, and that has continued.Harry Webster and Jane Correne are my grandparents.
Hope all of this makes some sense.If it does, I have more information about the Achesons of Pennsylvania. There were many Achesons settled in Penn.
Let me know if this matches any of your family.If you do get any info from your father and Grandmother, please let me know.I'll see what I have to match.I can trace the Acheson's back to Gosford, Ireland around 1400. I made the mistake of not starting this until most of my ascendants were gone so any help is appreciated.
