Hello Graham,
I have just started helping a friend research her mother's family, and wonder if it may be the same line as your Veronica's? My friend's mother (born 1907) had a sister called Veronica (nee JONES), born St Asaph in 1910. Name of father on birth certificate of my friend's mother = David Raymond JONES, mother = Maggie JONES. The family were living in Denbigh in 1907, but my friend remembers her mother saying that they grew up in Liverpool. There are likely other siblings to Veronica and my friend's mother.
Does this information sound compatible with what you know of Veronica's family? Please reply if you think it is a match, and we can compare notes further.
Kind regards,
Rebecca
