Cath., Jersey city>Westchester Cty 1914

Catherine A. Dollard, nee McDonald, was living in or near Mount Vernon in Westchester County, New York around 1914. I am wondering if anyone knows her parents?

She probably was married in Jersey City; born around 1940-1955, possibly in New York City or Ireland; she might have attended St. Michael's church in Jersey City.

I think she might be a missing sibling of my great-grandfather, Thomas McDonald, or otherwise connected to my family. All I know of Catherine is that she witnessed a marriage between Mary T. Winters and Terrence J. McDonald in Jersey City in 1868. Catherinesupplied an affadavit about the marriage when Mary became a widow and applied for a pension.

Sound familiar to anyone?
