Hi Dawn,
Thought I´d list you the few things that I know for certain:

Francis Patrick Walsh was born in Ireland and known as Patrick.
He married a Jewish lady.
They had a daughter who was known as Doreen Walsh (including on her marriage cert)
Doreen Walsh was born 19th March 1910, according to her death entry.
She married Herbert Allen in Preston on 7th August 1930.
Her father´s occupation was given as "able seaman".

regards, Gwen
