Not everything can be connected in Toobworld just because certain characters look exactly alike in different TV shows. (Of course, outside the Toobworld reality, this is due to casting the same actor over and over again.)
Case in point: Milton and Sylvia of 'Coronation Street':
I've claimed in the past that the characters played by Robert Vaughn on 'The Man From U.N.C.L.E.', 'The Protectors', and 'Hustle' were all siblings. But that doesn't mean that every character Vaughn played in "modern times" has to be of the same family. How many Duggar-like families can there be in Toobworld?
But Milton could be somehow related to characters played by Vaughn in other TV series, especially the one-shots. A role he had in an episode of 'Law & Order' could convincingly be connected to this American millionaire - as an identical cousin perhaps.
And although I haven't written it up yet, Stephanie Cole's roles of Diana Trent and Aunt Joan in 'Waiting For God' and 'Doc Martin' respectively are of the same family tree, but not officially. (A lot of out of wedlock children were born in the Portwenn area due to summer flings with summer visitors.) I don't think it's necessary to throw Sylvia into that mix as well. I'm sure there will be plenty of other opportunities for linking 'Coronation Street' to Toobworld as a whole.
So let's just enjoy this Milton & Sylvia romance while we can - which apparently will be for only three weeks.
Here's the first 'Coronation Street' episode in which Robert Vaughn appeared as Milton.....
