I am interested in your Mary Murray and Peter Cryan from Roscommon. I have a number of Cryans from Roscommon, mostly from Carrowreagh and Killukin area. John Cryan (1827-1904) married Honora Kearny (1831-1901). They had 15 children and at least one son and another grandson were named Peter Cryan. There may have been other grandchildren etc. named Peter as well. Do you have more details on your Cryans?
