It appears my original message didn't post, so if this a repeat, my apologies.
Heinrich (Henry) Schildt was born in Prussia around 1820. His wife Maria (Mary) was born in Braunschweig around 1825. They moved to Canada where at least one child was born, possibly three (my genealogy data is another computer that is currently shut down). They then moved to Saranac Lake, NY where more children were born. From there they moved to Milwaukee, Wisconsin.
During the Civil War Henry enlisted in a company made up of German speakers from Milwaukee. This was either company H or K of the 6th Wisconsin (Iron Brigade). He was elected Sergeant and served until he was wounded at Gettysburg on the first day of battle retreating through the railroad cut toward Seminary Ridge. He was shot through the left side with the ball exiting around his shoulder blade. He was sent home to recuperate, which took approximately 6 months. On his return he was elected Captain. He then served until the siege of Petersburg, Virginia, where he was again wounded. The war ended before he recovered. He then returned home, which was by then either in Milwaukee or Mazomanie (about 25 miles west of Madison, WI). He served as Mazomanie's Postmaster from about 1878 to 1886. Henry died in 1911.

One son was listed as having left for Montana. Another was said to have moved to Cimarron, California. One daughter I think married into the Appleby family in either Duluth or Minneapolis/St. Paul. Their eldest daughter, Augusta, was my wife's great-grandmother. She married George Pugh somwwhere around 1870. Once I get my computer's data moved over to my current computer I'll have that data handy.
I hope this answers a few questions you may have had.
