Rosselson scoresheet. White's name is written on the scoresheet, not in Leon's
own handwriting, so presumably by the player himself, but is utterly illegible.
It seems to consist of about four letters, the 1st maybe T or F of V, the 2nd
maybe "o", the 3rd maybe "g" and the last perhaps "l" or "e" or "t". "Vogt"?
"Vogl"? Later... another game, three days later, was against a player called
Feigl - I'm going to assume this is the name - JS. I think his original name
was Conrad Kurt Feigl but he eventually became Charles Feigl and then Charles
Kenneth Field. Team results: G Jessup ½, T Landry ½, L Rosselson 0, N Dor ½,
