Dolores Costello was an American actress. She was the daughter of actors Maurice Costello (Maurice George Costello) and Mae Costello (born Mae Altschuk). She had two children with her former husband, actor John Barrymore (born John Sidney Blyth). They are the paternal grandparents of actors John Blyth Barrmore and Drew Barrymore. Her stepdaughter was actress Diana Barrymore.
Dolores’s paternal grandfather was named Thomas Costello (the son of John David Costello). Thomas was Irish.
Dolores’s paternal grandmother was named Eleanor “Ellen” Fitzgerald (the daughter of Thomas Fitzgerald and Anne). Ellen was Irish, from Leighlinbridge, Carlow.

Dolores’ maternal grandmother was Katherine Rose “Katie” Callender (the daughter of John Callender and Elizabeth Casey). Katherine was an immigrant from England, born in Barnsley, Yorkshire. John was born in Liverpool, the son of Thomas Callender. Elizabeth was Irish, from Armagh, the daughter of William Casey.
So, Dolores was at least 62.5% Irish, and 25% German. I don’t know the ethnicity of John Callender, the surname can be Scottish or English I think.
Also, Louis Altschuh was from Rechenbach, Bavaria, the son of George Michael Altschuh and Anna Marie Renck.
And Eleanor “Ellen” Fitzgerald was from Leighlinbridge, Carlow, Ireland, the daughter of Anne and Thomas Fitzgerald.
