I am a descendant of Reuben & Margaret Lenharts marraige.

Question

Reuben and Margaret Lenhart are my great-grandparents. I'd like more info on them.

Answer 1

In order for someone to help you, more information might be needed. 

Do either of these individuals have WikiTree IDs?

There is a Reuben listed b. 1840 has no spouse noted and a Margaret b. 1920 but that is certainly an unlikely couple!  Is either of these people an ancestor you are looking for?

If neither is a match, you should add any of the following that you might know:

Location:  Country  > Province/Region/State/County  > City, town of b, m, d.

Dates or approximate dates of birth, marriage, death.

Names of parents, siblings, children.

Good Luck
