I am looking for any information I can find about a John Crawford that migrated to the U.S. to Ohio, from Ireland, but I don't know when. He had a daughter Mary Crawford (Marshall) that was born in 1825 in Ohio so that narrows it down a little bit, probably between 1790 and 1825. I also believe that he was a farmer.
I don't have a wife's name but his daughter Mary Crawford married Edmund Marshall of Pennsylvania (possibly in Ohio) and they then moved to Bad Axe, Wisconsin where they raised their family.
Edmund Marshall was the son of Lazarus Marshall (who I am also looking for) but all I have is that he was from Pennsylvania and may have been born there, Edmund was born in Pennsylvania in 1817.
