"The Seiferts of Hamilton, Fairfield and Cincinnati Ohio"

My Great-Grandfather Adam Seifert was born in Bavaria Germany and immigrated to the United States in early 1800 via the port of Philadelphia. I believe he had three wives, two of which proceeded him in death. Adam and family first settled in the Mill Creek area of Cincinnati and then later settled in Hamilton, Ohio. His first wife was Maria, last name unknown. I believe Adam and Marie had children (number and names unknown. No information what happened to Marie. His married his second wife Margaretha Schemich on 18 Sept. 1849 who later died. His third wife was Lena Wintz or Wertz, she had several children from a previous marriage. Jacob and Lena were married on 12 Oct. 1875. The couple had one son, Jacob (my grandfather). Adam died from an industrial accident on 5 May 1879, in Hamilton Ohio. Later Lena Wentz married a Hudson, first name unknown. Attempting to identify other members of the Seifert family, I believe many Seiferts in the Cincinnati area are related, I could use some help completing the Seifert family tree in the Philadelphia, and Cincinnati/Fairfield/Hamilton with the Seifert name in that area. Thank You, Adrian Seifert (please e-mail me at aseifert@ameritech.net if you have additional information.)
