The Margaret Dorward in our family tree was born 1-28-1793 in Arbilot, Scotland.She died 2-12-1822.I don't know who she married; this is a piece of the puzzle I am still working on.
Since we are 13 years apart on birthdates, I don't think there is a connection. If you think there might be one in a previous generation I'll be happy to exchange what information I have with you.
I will email you the descendants of William Dorward, from a Dorward researcher who sent the information to me, if you will let me have your email address. Perhaps there will be a connection there for you.
