I think I already submitted response. Learning to navigate the site. All info you found matches what I have been able to determine. Didn't have date of marriage between Frank and Mary Jane. Also, have never seen the name Gilday before. Notice on the census that there is a small boy, Matthew, living w/Mary Jane @ Michael Moran's house. He is the child, and my grandfather, of Frank and Mary Jane Moran Smith. It is info re Francis Patrick Smith that I can get no further than born in Ohio. He must have died shortly after marriage to Mary Jane. Wondering where his death certificate is or how he died. He is the person of most interest. Tks for info you sent. Great job! Pls stay in touch.
