Thanks for your update. A couple of dates differ between our files. Mine are mostly based on census which can be notoriously off (they seemed to lie and made themselves younger!
I show John Drain marrying Elizabeth FRANTZ (appears spelt differently on documents, this spelling from marriage info). I show they had a daughter Jane b 1875 which you don't list.
Children of James Nelson Drain and Ellen Cross are the same, but instead of Pearl, I have Vera Edith (?). I have a copy of the newspaper article on the fire if you are interested.
Was unaware of children for James Nelson and Bessie Delain. Can you update? I also have newspaper reports that Ellen took James to court for bigamy. He was "married" to Bessie and still legally married to Ellen. The newspaper reports follow the trial, her mother's testimony etc, and the last item is that sentence will be passed. Then I can't find the final article! I can send you copies of that info as well....
