Looking for any descendants of Antoine/Anton BOGNER and Regina BECKER, Antoine/Anton BOGNER and Agatha HAFFNER, John BOGNER and Mary ZAHM, William Frederick BOGNER and Annetta HAACKMAN/HACKMAN.

My gg-grandparents were Antoine/Anton BOGNER and Agatha (HAFFNER) BOGNER. Anton came to the U.S. abt. 1841/42. Rumor has it thru Castle Gardens.
Anton bought land in Section 26, Thompson Twp. in Sept. of 1843.
Is there a way to find/see this record of purchase? It is believed that
Anton came to the U.S. around 1841/42 with his 2 boys, Joseph and Louis, and
wife Regina BECKER. It is also said that Regina died aboard ship along with
her newborn infant, Martin. They supposedly were buried at sea. Anton
married Agatha in 1846.

Anton BOGNER died in Thompson Twp. on May 17, 1883. Is there a way for me to
find/see his obit or death record? To find where he might be buried? I
thought that they belonged to a St. Joseph Parish, but that they merged with
a St. Mary's Parish. I looked in those cemeteries, but didn't find them.

Very willing to share whatever I have on these families!
Thank you!
Joyce
