Who did Alice Mary / Mary Alice TAGGART marry?

I think the correct husband for Mary Alice Merrick (Taggart) is Willliam John Edward Merrick

This profile has incorrect name, wife and children William John Merrick

The son of
James Robert Merrick and Martha Louise Merrick was "William John" Merrick -- no Edward in his name in any documentation that I can find.

NSW Birth registration 19383/1871. parents James Robert and Martha at Wollombi.
NSW marriage registration 12143/1908 Merrick, William J and Medhurst, Lilian M at Singleton.
NSW death registration 15260/1938 William John, parents James Robert and Martha Louisa at Singleton.

His correct profile is on geni though without parents. It is attached correctly to his spouse Lillian May Medhurst
William John Merrick
