Eadaoin and myluck good call, it was against canon law at the time to be married during Advent and Lent. I knew about Lent, it seems to be why February was such a popular month to get married in, but I wasn't aware it applied to Advent as well.
They must have been in a rush to get married. The baptism record for their first son isn't available, no baptism records for those years, so I cant fully claim my first shot-gun.
I still have to upload a scan of the register for the other thread. I need to get on that and I'm still confused about the n.p. t.v. beside the baptism for another son born in 1861.
