Ancestral Family Tree DNA Testing / Identifying someone with a really large DNA match

Should be easy shouldn't it?
I tested with Ancestry some time ago and uploaded my raw DNA to as many sites as I could, one being MyHeritage
Every so often they email me to say I have matches, but today I got a message to say I have a close match. I looked, and the match is 665.7 cM across 21 segments, the longest being 64.1 cM.
My biggest on Ancestry is 546 cM across 16 segments, Longest segment: 115 cM. (My first cousin's daughter)
Even though Ancestry does a little pruning and is not quite comparable, my new MH match is pretty close, but I cannot identify him at all.
He has a tree with only himself in it giving his birth year. He has a surname which doesn't appear anywhere in my tree -
He's in his 20s and I'm in my 70s, so that excludes a lot of relationships. I have no children, I have one sibling who has no children, so that excludes great nephews.
I can see from shared matches that he would be related to my paternal grandfather's mother's line, so that excludes the only first cousins who could have a child in their 20s - they're on maternal side.
I can find two possible births which fit his year of birth, one has a mmn the same as his and location is better fit. The other has a different mmn, but I cannot find a marriage for parents. Possibly his father married a widow or divorcee so her surname at marriage is different from her maiden surname.
Can't find him on Electoral register, probably chose not to be on public register
So Facebook is my last resort I think!
