I believe that we are related. My great great grandmother was Mary Ann Langton Morrison of Castleton, Staten Island (daughter of Michael and Margaret Langton - originally of Sligo). Mary Ann was the first cousin of your great great grandmother Sarah.
The information that you previously shared in this message chain has been very helpful. Thank you. I was just curious as to whether you have found any new information about the Langtons in Ireland? I haven't been able to find out too much information about their origins in Sligo.
Any information that you could share would be most appreciated.
