My ancestor Ethel died in Sonoma, California, in 1980.  It was a surprise to find that out.  What was she doing in Sonoma at 97?  The last I knew was that she was living in Wiltshire, England, in the 1950s with husband Percival John Ford.
Can anybody advise me on US databases I could search to find out when Ethel went to the US and where she lived?  I've tried Ancestry.
