Reporter,
I can elaborate a little to help with your question about Miriam Matilda (Yemm) Crone Probyn.

Miriam was born July 1869 (I saw on Ancestry.com) & I have to assume in Drybrook. Her parents are Timothy Yemm & Mary Parsons who were married 7Apr1871 at Drybrook Parish (found on this site). Then they had Susannah in 22Dec1871 & by 1880 they were in Fulton County, Illinois.

Miriam was first married to William Burgdorff Crone and had 6 children. He passed away in 1920 and she married Fred Probyn & he passed in 1926. I have tracked Miriam Probyn to Peoria, Illinois in 1930 living with her daughter, Ella McLaren. In 1935 she is living back in Peoria and that is the last I have of her. Someone on the internet claims she died over there in Gloucestershire, England in 1936 but I don't know where to get obituaries over there to verify that.

I hope this helps find her, and please let me know if you do!!!
