I am searching for family member of Marie (Keogh) Swan. She was born in NJ with the last known residence of Long Island NY (?) around 1950. Marie had two brothers: John F. Keogh and Anthony F Keogh.

Brother John lived in the Miami Florida area, while brother Anthony was a NY City Police Officer.

Marie's father was John F. Keogh and mothers name was Sarah(Thorton). In 1910 census, the family lived with Sarah brother John Thorton in NY.

I see a private family tree out there that I believe is the Marie Keogh that I am looking for, but I cannot contact the owner nor can I see the records

Any information on Anthony, born around 1905 would also be appreciated
