I have spent a lot of time and money trying to find a marriage of John O'Brien to Ann McMahon, probably in Glasgow, Lanark before 1886, when John died. I have a rather narrow time line for it, as it appears John was with his mother and sister in the 1881 census, and unmarried. When he died, his registration lists Ann McMahon as his wife.
The only marriage for these names in this time line occurs in Blantyre and the parents for John as well as his occupation are incorrect. His parents should be Thomas O'Brien and Mary Glancy. Also I have searched a bit, and there was another John O'Brien in Blantyre in the 1881 census as well as an Ann McMahon with the correct parents for that registration living in Blantyre. So it seems this is not my couple.
As for Ann McMahon, I have a possible death certificate for 1916 where she mentions her parents are John McMahon and Martha previously Stevenson, MS McMahon (I also found them with unmarried daughter Ann in Glasgow in the 1881). It also mentions she had been married twice, the first time to to John O'Brien (labourer) which was always what John was noted as. The second marriage was to William Ronald which took place in 1901. The parents listed there differ from the previously mentioned marriage registration to John O'Brien in Blantyre so it seems obvious they were two different couples.
So...I can't find a marriage for my John O'Brien and Ann McMahon. Have I missed something...I have tried all sorts of wildcard combinations but nothing even close comes up. I would like to be absolutely certain that they never married before I enter it into my tree...so I thought I would post it here, because I know if there is anything to find, you guys will find it!!!
