Mary Whitney married John B. Collins in Christian County in 1860. In the 1900 census, she had a daughter, Louisa Trusty, (married name), who had a son Leon. In same census, she had 12 children, 3 living. One of these, William, born 1868 in Illinois, married Mahala Ferguson and they had a son Clyde, born 1897 in Kansas. In same 1900 census, William and son clyde lived at John Collins' boarding house. William hand Mahala had divorced. John collins may have died in 1904 and his wife Mary may have died in 1907. Possible buried in Odd Fellows (or IOOF) cemetery at Ponca City, Kay, Oklahoma.

My problem is I cannot find William Collins or his half-sister, Louisa Trusty after 1900. Can anyone tell me where they went?
