From what I saw on Wikipedia it appears that Robert, his brothers, and his father were all hockey players and may also have Wikipedia entries, so that is one place to look.
There is a possible father for him on FamilySearch, showing as deceased with no source. I'm going to look more at that FamilySearch tree because there are some discrepancies (e.g., possible father's brother with last name spelled with two t has different parents on his death record).
