Isabelle Symieson
Sister of Janet Symieson Peters. Church ordinance records and the Utah census prove she was in Salt Lake City by 1850. She was baptized at Salt Lake City on 22 September 1850 (the record is unclear as to whether this was a first baptism or a re-baptism.) The 1860 Utah census and her death records give her married name as Maxwell but it should be Mikesell.
In some sources her maiden name is spelled "Sympson" and "Simpson."
