RE: Dolores Costello Yes, I knew they were Drew Barrymore's ancestors. It is all so interesting! Dolores was so very pretty. I think you would be very lucky to be related to her...and she would be just as lucky to be related to YOU!
Dolores Costello In Wikipedia it gives the following information on Maurice, her father: Maurice Costello (February 22, 1877 - October 28, 1950) Born in Pittsburgh, Pennsylvania to Irish immigrants Thomas Costello (born 1852) and Ellen Fitzgerald (born 1853).
You probably already have this but hey...just in case!
