McNamara Family

Hello, looking for any further information on the McNamara family. My father was adopted to the U.S. from the St. Patricks Home in 1959. His mother's name is Mary McNamara (also seen spelt Marian McNamara). She was born in 1935 from Mace or Mulling. She is the daughter of James McNamara (born 1879) and Mary Garrahan (born 1898) - who were married on the 27 of January 1927 at the Church of Legan, Abbeyschrule, Mallymahon, Longford Ireland. James is from Mace (Glenlough, Westmeath) and is the son of Peter McNamara and Bridget Weir. Mary Garrahan is the daughter of John Garrahan and Anne Lynn.

His father is unknown but we have had great matches on his paternal side (potential name Wards), however we have not had great luck in actually contacting them. We do know he has at least 3 half-siblings - Patrick McNamara, Connor Ryan and Catherine Ryan (his mother was later married to a Ryan and had two children). His brother Patrick was also raised in an orphanage by the brothers a few years before he was born and we are unclear if they have the same father or are just half-siblings (Patrick passed around 2012/2014 in Ireland).

Any information or help to figure out more about either parent side is much appreciated!
