Thank you for the quick replies, and the welcome.
Eileen married John Flaherty. Her dob is between 1908 & 1912 (different on marriage & death cert).
There are several Eileen's so trying to trace father first. No idea who mother might be.
Marriage cert shows her living at 35 Harding Ave, Birkenhead, John Flaherty in Queen's Buildings (working on the tunnel).
I'm hoping Eileen didn't live alone, hence wanting to check the e-rolls.
