Looking for information on John Grennon Rosscommon 1854
Hello I have recently been in contact with a distant relative through a DNA match. He has previously used this message board when he was looking for information on his Grandmother Elizabeth Grennon born 1869 and Great Grandparents. These were Bernard Bryan Grennan born 1840 and Catherine Callahan (Callaghan) Bellanagare
A previous reply on this message board stated that Elizabeth's godparents as Joanne (John) Grennan and Brigida Tighe and added this information 'John & Michael Grennan was Bryan's brothers (see John Grennan of Tully just southwest of Bellanagare)'
I am looking for information with regards to my GG grandfather John Grannon born in Roscommon around 1854. The only documents I have are census records from England stating his Birthplace and Marriage Certificate 1876 Stoke-on-Trent to Maria Duffy from Co Mayo. On the Marriage Certificate John's names his father as Bryan
However I do believe that this John Grennan mentioned in previous replies to posts is my GG grandfather due to my shared DNA link to Elizabeth's relative. If anyone has any information to confirm if Bryan was John's father or brother or any information about John and which Parish he lived in would be really appreciated as I am hitting a brick wall . Thank you so much in advance
