I am Robert Gordon's sister. Your family information is quite interesting. Herbert B. Healis, my grandfather was born September 28, in 1878 in Edgartown, MA. Edward T. and Eliza Jane (Matthews) Healis also had eight other children. As Robert mentioned, Eliza Jane was Chappaquiddick Wampanoag. Perhaps we can share additional information. There are several family members that would be interested the genealogy information that you have mentioned. I also have access to a photo of Edward T. Healis.
