EUREKA! My friend, you have cracked it. Here in the marriage record you've just posted are David Lowe's parents names, William and Mary Lowe.
1850 Mount Pleasant, Green, Wisconsin William Lowe 45 b about 1805 Virginia Mary Lowe 43 b about 1807 Virginia Benjamin Lowe 18 Joseph P Lowe 16 David Lowe 14 b abt 1836 Ohio <--------------- Sarah Lowe 12 William H Lowe 10 John C F Lowe 7 Cyrus Lowe 5 Mary E Lowe 1
In 1860 this family is in Greenfield, Monroe, Wisconsin; David is grown up and not with the family. In 1840 only heads of household were listed in the census, so David would not be enumerated at that time.
1860 Greenfield, Monroe, Wisconsin Post Office: Tunnel City Mary Lowe 53 born about 1807 Pennsylvania William H Lowe 20 John C Lowe 17 Cyrus L Lowe 15 Mary E Lowe 13 Susan Sandelin 8
1865 Wisconsin state census Hixton Town, Jackson, Wisconsin David Low Number of White Males: 1 Number of White Females: 2 **This would be David, Hannah, and Susanna
Likely Susanna is a child of Hannah Hutchins from Hannah's marriage to Mr. Cleveland, since she was born ca 1860, before the 1863 marriage of Hannah to David Lowe.
Below is Hannah (= Hannah Hutchins m Cleveland m Lowe); this 1870 census was also posted previously.
1870 Hixton, Jackson, Wisconsin Hannah Lowe age 31 born Louisiana Susanna Lowe age 10 born Wisconsin Jane E Lowe 4 Wisconsin(= Jennie Eliza) Rosali Lowe 3 Wisconsin George Lowe 2 Wisconsin(= "your" George) Peter Jacobson 42 Norway
I wonder if Susan knew she was born before Hannah and David married. Some children don't.
