Will do, Trish.
In the meantime, is there anyone with access to the parish records of St Leonard's, Beaumont, who would be kind enough to try and find out
(a) if Emma Wyatt was baptised there c 1838, rather than at Great Oakley, and
(b) if she was buried there in 1930, as her husband was in 1914.
I'm still puzzled that Emma's birth cannot apparently be found in the GRO index, although, as I understand it ,she was born after registration became compulsory (in 1837?). Perhaps she was one of those whose arrival in this world simply was not registered. But, as she lived until 1930, you'd think she'd have required documentary evidence of her existence at some stage in her long life!
