Re: Charles McNamee (1856-1923) and his family

I am trying to find information on James McNamee's wife.In the 1870 census she is listed as Clara and in the 1880 census she is Cora.My great-great-grandmother was Clara Vanderbilt.I know she was a cousin to the famous 5th Avenue Vanderbilts and visited the 5th avenue mansion weekly(I don't know which mansion there were several).I know this because my great grandmother said she remembered visiting the mansions with her mother as a child.Was James McNamee's wife Clara Vanderbilt? Daughter of Jacob Hand Vanderbilt? Any information you could give me regarding James McNamee's wife would be appreciated.
