Rudolf Janda was my great-grandfather through his daughter Elsie, date of birth June 9, 1914. I can confirm that Rudolf was a tailor in Chicago and they lived on Avers Ave.

Elsie married Albert Harkey and they were farmers in Bainbridge Township, Michigan.

I have recent history but am more interested in their Bohemian/Czech connections, of which I know nothing. Those letters would be of particular interest.
