A DNA question that concerns a friend not me

[Margaret in Burton]

My friends husband recently had his DNA done via Ancestry. His situation is complicated. He thought he was adopted but now we realise he wasn’t, he was brought up in a family group home in the North East by a couple he thought were his adoptive parents but now realises they were just council employees. He feels his whole life has been a lie. He grew up with their surname as his, so has no idea what his real name was.
His DNA profile, which I haven’t seen myself, shows Scandinavian, Scottish/Irish and south of England Ancestry. Apparently it tells him he has two connections in the 1920’s who emigrated to Australia. He wasn’t born until 1954.

Any advise please? I know nothing about DNA. I do have an Ancestry sub which my friend doesn’t have.
