We met on the Sligo page re workhouses. My Co Clare ggrandmother was Annie St Laurence of Ogonnelloe (married to Michael McKenna of Ballyloughnane, Ogonnelloe.
Unfortunately the Clare Heritage Centre was unable to find any record relating to their marriage.
A John St Laurence was one of the sponsors of my gfather's sister Mary McKenna on 13 Aug 1869 and was probably my ggmothers brother. The John St Laurence who was a defendant in the case you cite could well have been my gggrandfather.
The farm next door to my ancestors farm in the townland of Ballyloughnane (sold out of the family in 1997) is still occupied by a St Laurence family.
Due to lack of records I have not found out who my ggrandparents parents were.
Just about all the land in the Parish of Ogonnelloe was leased by the Purdon's, whose name features prominently in wall plaques in the Irish protestant church in Killaloe. One to William Causabon Purdon as well.
I keep finding info from you on the web. Great research and most helpful Thanks. Kevin McKenna
