I found a Simeon Burch born about 1830 in Indiana, married to Maria or Mariah Lawson, born about 1831 in Indiana, with the following children.
1.Lydia Burch 1853 IN
2.Elizabeth Burch 1855 IL
3.Franklin Burch 1857 IL
4.Jane Burch 1857
5.Alice Burch 1860 MN
6.Henry Burch 1862 MN
7.George Burch 1864 MN
8.Charles Burch 1866 MN
9.Ida Burch 1868 MN
10. Maggie Burch 1872 MN
11.Anna Burch 1875 MN
12.Simeon Burch 1877 MN

1850 Census- Indiana, White, Dist. 130
1860 Census -Minnesota, LeSueur, Ottawa
1870 Census- Minnesota, Renville, Flora
1880 Census- Minnesota, Renville,Flora

This seems like a better fit for this family, and the name Simeon is a little unusual.
