I have checked my info at home.Rebecca Atherton who married David Coray was the daughter of Elisha and Eunice (Carver) Atherton. Elisha was the son of James and Elizabeth (Dormant) Atherton and a great-great grandson of James Atherton born 1626 probably in Wigan, Lancashire, England.It has been suggested that James was a brother to Humphrey but that couldn't be so since Humphrey's father, Edmond,died in 1613.Entries at Ancestry.com give David's parents as John and Phoebe (Howe) Coray. Rebecca and David had at least one daughter, Celinda, married 1 Sep 1836 to Job J. Harvey.
Maria Atherton who married Ira Coray was the daughter of John and Mary (Fulkerson) Atherton.John was a son of Cornelius Atherton and also a descendant of James but through another great grandson of James, John Atherton born 1709 in Lancaster MA.Ira Coray was also the son of John and Phoebe (Howe) Coray.I don't have any information on their children.
I do not have any information on the Behms unfortuately.
If you would like additional information please let me know and I can send it via e-mail.
