Elsie was born in 1916-17 in Nantwich, Cheshire. She may have a brother Henry and he is the one that has been found through probate however I don't feel this is the Henry Furnival that I am looking for. There is a 16 year old Henry (1911) living (and born) in Nantwich who is, I suspect, the Elsie's brother in question, so we go back to the most likely (before m. cert proof) candidate Henry (1905) born in Runcorn son of Joseph & Margaret.
Thank you again for all you input, it is much appreciated.
