Hi, I know it's a while since you posted this but hopefully you'll see this reply. I'm not sure if we may be related but I was standing in front of that grave last Saturday! I have a photograph - not very clear - of it if you would like a copy. My grandfather is buried right beside it and is also a Cullen. We were trying to figure out if William and Esther were related to us. (It may be conincidental that the two Cullens are side by side). My great grandfather would have been Charles Cullen married to Kate Barry, they would be on the 1901 census. We don't know the names of anyone before that on the Cullen side so if this is the same family, I'd appreciate any info.
