Researching for another on Maternal line.

Seeking info on this Family:

Johann came over from Brandenburg area in 1854-1855 to Dodge Co.

CHILDREN:

AUGUSTA E. 1864 married Dodge Co. March 16, 1887 unknown spouce.

JOHN F. 1867-1947 Dodge Co, Wi. married Emma Pasbrieg Feb 26, 1889 Dodge Co.

In pre 1907 Vital Records we found:

Augustas' marriage-assuming is our Augusta.

Marriage in Feb 1861 for a John Dohrmann to a Henriette Lehmann in Dodge Co. Wondering if they could be related?

Death for a Henriette Dohrmann Feb 2, 1904-Dodge Co. Wondering if that could be ours.

Any help on this line would be deeply appreciated. I am just starting research on this line.

Thank you so much,
