I don’t know if you have ever used the 1837 online GRO index? I haven’t…..yet….they have recently changed the site a little to try to make it easier and more cost effective, i.e. less pages for each search. At the moment they are giving people a free search, year 1868 for births There is one birth for, Elizabeth Mary Edgson, Pancras, 1b 129
You can also search the Regimental Births Index GRO REGIMENTAL BIRTH INDICES (1761 to 1924) www.1837online.com
I found Elsie G Edgson born 1896 and Gladys Edgson born 1899, the place name was both Deritend
There is a place called Deritend near Birmingham, as you have Edgsons who were in the army I wondered if these might be some of yours?
Well that’s all for now, nice to hear from you, don’t be away to long!
