I have found Eleanor in 1921 and 1939. In 1911, I think she was a nurse at Winick Mental Hospital, near Warrington, Lancashire. There is also a death registration and Probate.
On the 1911 or 1921 censuses, I cannot find Henry Richards, nor can I find a death registration. A newspaper article said where he was living in the early 1900s, so Electoral Registers may list him, and a visit to the library. In wanting to move the family line forwards, he is not my main interest.
Something clearly happened. Considering the information found, I find it strange that both Henry and Maggie totally disappear. Maggie was performing and competing until 1903, age 23 and then there is no mention of her, at least as Richards. I cannot find her on the 1911 or 1921 censuses in Wales or England and no death registration. The other options would be marriage, or emigration. In 1903, she was still performing under Miss Maggie Richards. I have checked two marriages registered in Newcastle Emlyn 1901 and 1909, with possible husbands Davies, Lloyd and Morris. She is not listed on the 1911 or 1921 censuses under any of those names. For someone performing and mentioned in newspapers, I would have expected a marriage to be in the newspaper. Maybe she did not officially marry, but assumed his name. Performing in other areas, she could have met and married elsewhere.
As I cannot find Maggie, tracing that line forward is on hold, as I do not know where to look next. Thanks for the responses.
