According to Family Search Int (LDS) Solomon Silkwood was born in Europe in 1759 and was the father of Barzilla b1790. The Silkwood family moved from Kentucky to Franklin Co. IL about 1800. I will send you my sister's email address and see if she knows. My guess is that the name is English or Scots. There are still a lot of that family in Franklin Co. where my sis lives.
