I have also found information about Erasmus Zerkel being the son of Abraham. My great-great-grandfather was Erasmus Zerkel, born 18 August 1829. He was the son of Michael Zerkel and his wife, Margaret Good. He was born in Virginia and came to Champaign County,Ohio with his parents and siblings. He lived in Mad River Township and is also buried at Terre Haute. He was married 1st to Barbara Ann Zirkle in 1854. In 1857, he married his 1st cousin Rebecca Shaffer and had 3 children. Zacariah, my g-grandfather and 2 girls, Leanne and Amanda. As far as the mystery about Anna Getz, I have her listed as Nancy Getz, b 7 Oct 1801 in Lancaster County,PA.
