murphy from Drogheda to USA

I would love to know what happened to James joseph Murphy of Drogheda.

James Joseph Murphy was born in Drogheda in January 1881 to Thomas Murphy and Margaret Ellen nee Rooney.

I think he may have been known as Joe in the family. They lived in the North Rd./ Trinity St. area.

Some time after his father died in 1891 ,the family moved to Co Wicklow from where James Joseph emigrated in 1899.

He left for New York with his sister Alice both going to their grandmother MrsFlynn at West 27th St.

His younger sister Mary followed in 1907.

Alice married Otto Rudolph.

Mary married Thomas Walsh.

James Joseph's mother remarried in Ireland and became Mrs O'flaherty.

 I would like to find his decendents but I don't know if James Joseph married, had any children or ever returned to Ireland..
