It is very complicated but I think you are from the other Crottys. As you said mine are the Ross, County Clares but I have stayed with your relatives in Kilbaha. I have been told by the Gorman family that not only did my ggggrandparents marry (Timothy Crotty & Mary Gorman) but Catherine (Kate) Gorman married Michael Crotty and they ended up in Lancashire England but the other Gorman girl Bridget Gorman married Patrick Crotty and they also ended up in Lancashire. So it works out that 3 Gorman girls marry 3 Crotty boys!!!! Now you can see how confusing it is. I know Kate Gorman's family ended up in the USA and of course Mary Gorman's family ended up in Australia. I am not sure whether Bridget Gormans family ended up but I know some of your family moved between England and Ireland.
I can't believe that somewhere their has to be a connection but your relatives living in County Clare at the moment do not think so??
