Following the query on Trophy-winning managers I've received a message from Graham Deans which suggests Frank Heaven was Thirds manager in 1903-04 when they won the league. The only online reference I can find is a wikipedia article claiming he was manager at Cathkin in 1904-05 when Thirds won the Scottish Cup.
As stated ad nauseum I find wikipedia an incredibly dodgy source of information so any other verification of this would be welcome.
However this forced me to look at my notes for Third Lanark managers and while I thought I had a fairly comprehensive list it seems there are a few outstanding queries which I list in italics below in the hope that they can be cleared up.
