Hi Marmaduke, I have not seen that tree on Ancestry, but will have a look now. Sadly this is a different Bernard Coll. He was born c. 1875, but lived all his life in Ireland. We had a date of birth for Rosaleen, Nov. 10, 1924, so I am not sure which year is correct, but I think most likely 1924, as a sister was born March 1923, who died as an infant.
Thanks to you and everyone who has responded, we will crack this one eventually.
