Assuming her Father was George Hollingsworth I did find a Mary Hollingsworth born 1923 in Nottingham where George was born. I also found a Mary Hollingsworth who Died in Keighley, Yorkshire in 1998. She was around my Mother's age and died before my Mother who died in 1999. The best I can do is assume she was born after her Father's marriage if he was married at age 20 or 21 possibly around 1919 or a little later.

Thanks for the reply, Wayne
