Thank you for this information. I had been aware of the Elvyn Larmon death, but not the location of his burial. I haven't been able to connect him to my family though, and am not sure about whether or not there is a link as all of the folks on my side seem to have been Catholic. With regard to the census information, the Larmons from 1911 are definite relatives, but the Catherine Larmon from 1900 is still a mystery to me.
I have not been back looking at this branch of the family for awhile, but process of elimination has made it seem more likely that the family is buried in Dublin rather than Kildare. Some of the surviving children moved there after marrying, and it's possible that family was originally from Dublin and had plots in a cemetery there. Our surname does not appear to be that common, but unfortunatey for me most of the family died in the years just prior to when death registers were kept by the Roman Catholic parish (Caragh) where most of the baptisms occurred.
