Henry Richards and Daughter Margaret

[Talacharn]

I found the 1911 census for Maggie, also living in Cross Inn, which says she was a Nurse and born Chelsea, London. It has to be them.
Henry Richards died Jul-Sep 1919 and registered in Aberayron. No Probate/Will.
There is a possible marriage Apr-Jun 1918 to John Lewis.
Two births registered in Aberayron, David R Lewis 1919 and Timothy Lewis 1920. With my limited access to the 1921 census I can find them in Upper Llanddewi Aberarth, but birth years do not match Maggie by at least 5 years. It might be a different Margaret. There is a Maggie Richards. b.1877 Llanarth and living in Llanarth, Aberayron. That person still seems to be living in Aberayron in 1939. I need to visit my library and download a few records.
