In the letter Lawrence introduces himself and hopes that Grace will write back. She does and they eventually get married. From that marriage they have 12 children. And in case you were wondering, Thys and Gertrude also were married.
Here is the full transcription of the letter, as best as I can make out the handwriting:
Ireton 26th Nov. 1922
Miss Grace Wichers = Downs, Kansas
Well I suppose you will be very much surprised to get a letter from somebody you've never heard of before, and I am sure you've never seen me either. But then that would not make any difference. I guess you like to know how I happen to know you. Well I'll tell you. It was a dark night once in the early spring this year, that my brother was cranking his Ford. I of course was wondering what was going on, but I found out that he went to Maurice to get somebody from the train. He came home late that night. The next Sunday he introduced me to miss Gertrude Wichers the one he got from the train as I said before. We are still very good friends. Of course my brother is a little better friend to her as you can imagine.
So you see that is the way that I happen to know you for she told me a lot about you. And while I know you I think you have the same right to know me also. Well I guess you almost know who I am now. My first name is Lawrence and my last is Broersma. I do not know if you ever will answer this letter, yet I'll be very much pleased if you would for the more friends a person has the less enemies he'll get. Garrett and Gertrude are making it fine. Gertrude is a true lady as you will know by this time. Now I will close this letter and see if I get the answer someday.
In doing so I call myself with greetings,
c/o R de Boer
