Just today, I got in touch with a descendant of the Jackson Co KS Bottom family, Edward Bottom of CA. I found he had some information in an ancestral file on LDS. He is LDS and was very glad to hear from me. John Bottom Levett, who came with Mary Clements and her children, named Bottom, came to U.S. at the same time, and both lived in IL, John Levett marrying in Peoria IL in 1865. He and his wife, Agnes McAvoy, moved to Pottawatomie Co KS, next to Jackson Co KS, where the Bottom family lived. We think Mary was his aunt by marriage, as his middle name was the same as her first husband. We believe Jeremiah S Bottom's sister may have been John Levett's mother, although we don't have knowledge of her. Edward thinks Jeremiah's father was William, his mother Mary.
