Silas and Hannah Lease Bitzer,Rowe,Carmean,White,Post,

I am researching the Bitzer family. Silas Bitzer was born in VA.around 1817. He married in Ross County Ohio to Hannah Leasein 1838.
They later moved to Fayette County around 1849. There children were
William, Anna Marie, Charity Jane, Mary, John, and Bunyan. Around
1865-66 Silas moved his family to Jackson County ,Mo. His oldest
son Wm. stayed in Ohio. He married a Mary McMaster.

Silas' parents may be John and Mary Elizabeth Rowe Bitzer. There
children were Silas, Harriet, Hannah, Dorothea,Sarah and John. Harriet
married Andrew Post,Sarah married John Carmean, Hannah married a Branen,
Dorothea married a John White.

I am seeking verification of Silas' parents and any ancestors farther back.

I have quite a bit of collected materials on various Bitzer's and
will be happy to share what I have.

Any response would be greatly appreciated.

Thank You,
