thank you Sarah, for your very full reply.
Some of that I had subsequently found, eg baptisms for Isaac and James, sons of John and Grace (BEAL) DAWE, and also today, sorted out which of the William and Mary FINIMOREs were likely to be Elizabeth Stockman FINIMORE's parents.
My further interest here being a possible HAMLEY connection, with curiousity aroused when I found a Sidney FUGE boarding with Frederic Cornelius DAWE in 1891 - if he's the Sidney FUGE I think he is, his mother was a Mary Elizabeth HAMLEYhttp://wc.rootsweb.ancestry.com/cgi-bin/igm.cgi?op=GET&d...
Certainly his birthplace, age and occupation are right, even if he is also enumerated on his ship.
Thanks also for the 1861 info, negative though it is, at least it's not just me.
Re the DNA, for the Surname dna projects we are testing Y chromosomes, which are only carried by the males, and passed from father to son, hence the direct male line DAWE requirement.
Other tests do other things, eg Family Tree DNA's family finder test for finding close rellies, but we're looking for Surname lineages and seeing how they may inter-relate.http://blairdna.com/dna101.html
may be of interest.
Pyworthy isn't too far off the beaten track for where my Isaac DAWE was at times, http://familytree.lornahen.com/p19570.htm
although most of his and subsequent generations were millers, not shipwrights, but who knows!
