You may want to check out the possibility that your Daniel
married to Elizabeth PERRIN, may have been the son
of John Secord Jr. b. Apr. 28, 1757 who was the son of
John Secord b. Oct. 11, 1725.
Possibly John Secord's will never mentioned Daniel because
Daniel was his grandson.
I wouldn't count this out.
Hope we can figure out this mess.
