I think you can find the info you are looking for by usin a book called "Imlay Family History" penned by Glenn Imlay of Zanesville, OH. If you are unable to locate a copy, I do have one.
I think you'll find that the spelling of "Imaly" is incorrect. I have found so many spelling errors on our name in the old records I have researched. On a trip to Scotland for research an old Galic woman put me on to how to trace all the misspellings.
I hope I have you on the right track. Feel free to contact me at firstname.lastname@example.org
