Thank you so much Megan! That's a wonderful chunk of information! I was wondering why I couldn't find my Gran's auntie Annie (Protheroe)! I'm unsure of Maisie, but I'll ask my Gran. I do know there's also a Llew (Llewelyn) Protheroe born to Ellen Lewis and Eleazer, but I couldn't find him either.
In regards to my grans half brother, his name was Elwyn, but I cannot find any details of his biological father anywhere because I don't know his name, nor does my Gran (I suppose Dilys kept it secret!). But I do know now that Annie Protheroe married Milton Dyer and moved to Slough, they adopted Elwyn when he was between 8-10 years old I believe.
Thank you for helping with this, I am still learning and finding myself in a lot of dead ends, but I cannot afford to buy certificates every time I have a query or am at a loss, I cannot afford even one. So I'm grateful for your time and help!
