Simon or Gusbarr/Caspar/Gutschow ? in Mecklenburg

Looking for any information on

Mary Simon or Mary Gusbarr born about 1831 in Mecklenburg.

She married in 1857 in Detroit to Charles Kruger (b. 1833).

On her marriage record her maiden name is stated as "Simon". On her burial record the maiden name is stated as "Gusbarr".

Are there any connections to Simon or Gusbarr or maybe that's a mispelling of Caspar or Gutschow.
