Brick wall Ancestor,Edward Blewett, b ~1825 in England. None of the Edward Blewetts born in England around this time pan out.
Distant autosomal DNA connections (6 - 8 cMs) to various matches with Blewett ancestors who all link up to the same ancestor.
Y-DNA has no Blewett matches. Have compared with one male Blewett descendant and they are different halo types.
I am looking for untapped resources, have used Ancestry, FamilySearch, My Heritage, Cornwall database among others
Any suggestions other than brute force, reverse mapping the Blewett family tree?
