I am also an Agnew of Lochnaw descendant. I am trying to trace my family's heritage and have hit a stopping block. I thought you might be able to help. My mother's maiden name is Agnew and her father was James Blanchard Agnew. His father was John Patterson Agnew and his mother was Roberta Blanchard. I am trying to figure out who John Patterson Agnew's parents were. I know he was born on 28 March 1879 in Pennsylvania (Philadelphia I belive). But there are two possible candidates for his father. One is Robert Agnew (born ~1846) from Ireland who came to USA in 1867 and was married to Ellan from England. The other is Nathaniel Agnew who was born in Pennsylvania.
