I tried sending this to you by e-mail, but the address was wrong. I hope you check this forum.
I'm sorry to be getting back to you so late, but I just now got arround to reading the responses to my query that I had forgotten I posted. You wrote: "I am a descendant of Donald Mackay (2) the Clipper Ship builder. He was born in NS. I dont know the date, but will e-mail you a list of his descendants. He moved to New York at age 15 or 16, and finally settled in Boston, ( his descendants are also in Maine) he eventually brought many of his siblings to Boston to work with him."
How certain are you that your Donald is the son of Donald, the Hector immigrant?
I have a private site at MyFamily.com for descendants of Alexander MacKay of Beauly, Scotland. Donald, Sr. would be his grandchild. On the site, I have a gedcom of about 2600 descendants. Others have contributed a number of pictures related to the family as well as a great deal of historical information. I would love to add the descendants of Donald Mackay (2) the Clipper Ship builder, and I'm sure that the other members of our group (about 20 of us) would love to hear from you.
