Query on Sarah DOVE

Sarah Hottinger
born 15 November 1791
died 12 August 1868
---------------------------------------
Query 1

According to her gravestone she is the daughter of Aaron DOVE. This gravestone appears to be a newish gravestone and in the media you can see another photo of an older worn gravetone.

She has two birth surnames noted - RIGGELMANN and BAKER - does anyone have any source documents for either of these names?

----------------------------
In Geni she has two husbands
1) Capt. Aaron Dove 1786-1848 married 21/9/1808
2) George Hottinger 1775-? (no marriage date listed)

Query 2
Her children to Aaron DOVE are born between 1808 and 1846
Her son to George HOTTINGER was born 15/6/1817 Reuben Hottinger

Whilst it is possible for Reuben to be the result of an affair whilst she was married to Aaron DOVE - she gave birth to a son Joseph Alfred Dove to DOVE 1 month before Reuben was born.

Are the dates on these two children correct? Can anyone provide documentation?
