Mark's Grandfather, Lou, played for the old WHL Calgary Stampeders in the late 50s and early 60s, scoring 57 goals in 69 games in 1960-61 as a 29 year-old. After he retired, he worked as a scout, based in Calgary, for various teams over 15 years.
He left scouting in 1993, and spent the final years of his life split between Calgary and the Tampa area (he must have loved 2004). He died in 2010.
