I've spent several years looking for the birthplace of Martin Conlin only to be at the same place I started...Roscommon Ireland, possibly. That's what I know, that's all I know and try as I might I've not been able to narrow that location down to a town or parish.
I've been doing what the books and research guides say to do; find as much information in U.S. records first. The main goal in that being the potential for a U.S. record mentioning the birth location of the individual in Ireland. Another goal is the possibility of finding the location in Ireland through a siblings or parents information.
I have collected several significant documents pertaining to Martin's life within the U.S.
County court index entry stating his first papers for citizenship were filed in July 21,1856 in Cuyahoga County Ohio
County court index entry for first papers state he arrived in the U.S. in March 1855
Marriage record from October 27, 1856 in Cuyahoga County Ohio
Naturalization document giving Oath of Allegiance October 27,1860 in Audrain County Missouri, witness John O'Dowd
Census records for 1860-1880 in Audrain & Linn Counties Missouri
Will dated March 9, 1896 in Missouri, witness John O'Dowd
Tombstone b: December 12, 1828 County Roscommon Ireland, d: April 28, 1896 Linn County Missouri. Burial in Linn County Missouri
Obituary May 2, 1896 in Linn County Missouri
Certificate of Probate dated July 19, 1897 in Linn County Missouri
The tombstone is the only piece of evidence that specifically states County Roscommon as Martin's place of birth. All other items state Ireland. None of the documents contain or make reference to parents, siblings, aunts, uncles etc. I have the obituaries for Martin's wife, Ellen and one of his children, Michael. Both state that Martin was from Ireland.
So...what's a genealogist to do? I will continue to look for documents created with Martin's wife and children in hopes of finding some other nugget of detail. I also need to search for John O'Dowd. John was the witness to Martin's Oath of Allegiance and his Will; perhaps they knew each other before arriving in the U.S.
Is there anything I'm missing? Some glaring detail that I should be looking for that I'm not? I would love to hear from anyone that has any suggestions.
