this might help you some;mary e.in the 1850 census is 1 yr old living with parents Lee S.& Nancy S. Alexander in Adair Co.,Mo. she was born in mo. and parents both in Tenn.----then in 1860 in Kirksville,Adair Co.,Mo. it shows her at 11 yrs old still with parents Lee&Nancy .---in 1870 when she is married to Jessie Swope age 21 still saying she's born in Mo.and the years match.Why she said she was born in Ky. in the 1880 census must be a mistake.Her parents show up still in 1900 in Linn Co.,Brookfield Township,Mo. Lee is 75 and Nancy is 72 with 3 children still living at home---Dora B. age 41 single--R.J. age 37 single and Nannie M.--age 30 and single.The spelling of the names may be a little off for its hard to read some of the spelling.Lee had a older brother David Alexander age 42 living close in the same county in 1850 .
