For a long time we could not find out what happened to Betsy after Hugh Crabb died in 1870. But I’m happy to report that I found her on the 1871 census staying with her daughter Harriet Denning at 193 Bristol Road, Bridgewater, Somerset. Cyrus Denning was a grocer and provisions dealer.
And then I found her death in Wandsworth in London where her daughter Hannah Jenkins lived, so there we are, she in not immortal any more. Here is her certificate if you want to add this detail to your family tree with my compliments.
