Hi Rob
Thanks for your help. I grew up with the story that the parents were gypsies. Newspaper reports described them as 'tramped about the country', the trade of the men - coopers. Or was Cooper their name? I have a detailed newspaper account which even mentions a neighbour noticing that my grandmother, aged 19 months, had been vaccinated 4 times. Yet, no one thought to ask names of the parents.
Couple #1 fostered my grandmother for a few months. I have their names and details etc. They gave her a name, Alice, because they didn't know her birth name.
Couple #2 adopted my grandmother informally (no legal adoption then). They baptised her with a new first name and middle name being the one couple #1 gave her. Have no idea if her forename, Eva, was her real name.
