This is really confusing. I have a copy of the city's record of their wedding certificate, the city official wrote "Houlton, Maine." The census records for 1910 specified Maine as his birthplace, but maybe you're right...I see that Maineville is in Ohio, not PA, but maybe there's a fair number of Danvers families there instead.
I contacted St Augustine's Roman Catholic Church where they were married. Maybe it'll have a record of the parent names and birthplaces.......I've actually seen that before, where the church records had additional records that the city records didn't.....
Thank you again!
