These were all in Coffey county Ks, in or near Burlington Ks.

Julia F. Sheets was my grandmother, born 1898. Her father's name was John, and her mother was Belle Cummings. She had an older brother names Lee. I remember him, a tall thin mild mannered man. I'm not sure where Belle comes from, but John was supposed to be from Germany or maybe his parents were. I'm not sure. He was supposed to have a cousin or nephew named William and another named Henry. I remember meeting Henry when I was very young.
I have some pictures of some of these people.
