Hello Keran, No relation. I'm very familiar with U.K. Birth/Marriage/Death records.I had a look to see if I could find anything re:your grandmother's birth ref in 1924 acc to details you gave. I believe I found only one ref for a Irene F.Pollard born in 1924 and reg'd in Birkenhead, Cheshire, U.K. This Irene had two brothers =
1.George M. Pollard born 1921. 2. Frank W Pollardborn 1923.
I found the mothers maiden name of the above children inc Irene F.Maiden name was STAVELEY.
In early 1921 a William D.Pollard married a Annie Staveley, reg'd in Birkenhead.
