Looks like Catherine Reynolds, nee Martin did marry James O'hara
birth of Alice O'hara, 5 May 1900, Broxburn, Uphall. Parents - James O'hara, retort man and Catherine, m.s. Martin (married July 14th 1899, Broxburn).
So the other three children in the 1901 census are the children of Edward Reynolds.
I like it when things happen as I think they might
