Family History Stalkers

[Phoenix]

My former boss's daughter wants to find family.

Well I have. Extremely elderly, on a public electoral roll, in a very well-maintained road.

The question is, do I put them in touch with each other? They have had nearly seventy years to contact each other, had they wanted to.

My gut feeling is that it would end in tears, that they will have nothing in common with each other.

Has anyone else done this for a friend, and if you did, did it work?
