Doing some quick looking around I see: The 1860 census has Levi Bearse, age 20, a shoemaker, born in New York, living in a rooming house in Union, Branch County, Michigan.
Levi entered the Union army as a private 9 August 1862 in Coldwater, MI.He was promoted to full corporal 1 Oct 1864.and left a corporal.He was mustered out 28 July 1865 Jackson, MI.He served with Battery A, 1st Regiment, Michigan Light Artillery.
One transcription of Levi's marriage record has him as Levi Bearss marrying Marilla Aldrich in Kent County, MI, 7 Oct 1865.
I see a Levi Bearss, shoemaker, in an 1884 directory of Cedar Springs, MI.And again in 1890.Same guy?
I don't know whether it's the same person, but in the 1850 census there was a family listed as Bears living in Roxbury, Delaware county, NY. Henry age 38 Harriet age 33 Mary Jane 13 Levi 10 Julia 8 Matilda 6 Amanda 4 John 1 Very suggestively, Henry is a shoemaker.He was born in Connecticut.Harriet and all the children were born in New York.
In 1840 there was a Henry Bearss in Stamford, Delaware County, whose family included one male 20-30, one male under 5, one female 20-30, and one female under 5.Perhaps they're the same crew.
