This is a bit of a family mystery/secret

It seems after my great granddad was KIA, my great gran had another child,
Alls that is known is that she went away for a few months and then came back and her sister ended up with a new baby.

For the time i would have thought the name was quite unusal, she was called Dhama (unsure of spelling)

This would have been after 1941 when my great grandad passed away.

I have my great grans name, maiden name and her sisters name (not her married name)

Do you think this would have been a legal adoption or a case where her sister took the baby on?

I cant locate the child on the census so i thought maybe i had the name wrong but after double and tripple checking the older generation said it was def correct
