Yes both "Whipper" and "Dropkick" would have been regularly reused monikers for wrestlers of the time.
Dave Mack appears to have wrestled likely in the 1930s, definitely the 1940s, likely the 1950s and retired from wrestling that decade
In the 60s to the 70s and maybe even early 80s he served as MC at wrestling shows
His long tenure in pro wrestling, 38 years at least (wrestled on a card in 1941, was MC in 1979) makes him a very interesting figure.
Would be very beneficial coming across a relative.
Info on a fellow called Cliff Donaldson who wrestled as Butcher Donald would be great too.He was a taxi man in Belfast I believe.
Kindest regard, Nick
