Eileen is Dad's youngest sister and was 14 years younger than him so she was around 9 or 10 when theses letters began. He sometimes calls her toots in the letters also. This was one of the few letters we have written directly to one of his brothers or sisters, I assume that all of those ended up in their possession.
I failed twice at trying to get a table into the blog. Not sure what happened but maybe you can figure out the game he is talking about even though the columns went back under each other.
