Did Albert Schweizer have any children?

Question:

Did Albert Schweizer have any children?

This girl in my spanish class says that her great-grandfather was Albert Schweizer. I've searched the internet, but I can't seem to find it. Please include names if possible.

Best Answer - Chosen by Asker: He had a daughter, Rhena, born in 1919. I don't know whether she lived to adulthood, married or had any children.

EDIT: I did a little more research, and found that she did marry, but I still don't know if she had children

Here's a picture of her with Jane Goodall, the famous "chimp" scientist.
