Sarah Ann Wisner was the daughter of William Wisner and Elizabeth Badgley.
Elizabeth Badgley was the daughter of Anthony Badgley and Mary Elizabeth Bookhout. Anthony and Elizabeth had 11 children and I have not been able to trace them all, however their second child, Mary (1776-1868), married Hendrick Bogardus, often referred to as Henry. Both the Badgley and Bogardus families started out in Dutchess County, NY, moved on to Albany County, NY and finally settled in Dewitt, Onondaga County, NY.
I don’t believe that Henry and Mary Badgley Bogardus never had any children of their own based on an abstract of Mary’s pension application I found at NY Finger Lakes Genealogy

Their bible records do not record any children of their own. Abiah Badgley was another daughter of Anthony and Mary Elizabeth Badgley. Mary is shown living with Henry P Bogardus in Dewitt on both the 1850 and 1860 censuses. The family group shown on the 1850 census is as follows:
Henry P Bogardus 56 NY
Elizabeth 54 MA
Polly (Mary) 73 NY
Henry 25 NY
Ira 23 NY
Eugene B 13 NY
Irene 14 NY
Rosemond 11 NY
Elizabeth Chapin 20 VT
On the 1860 & 1870 census for Noble, Branch, MI I find:
Henry Bogardus, born abt 1825 NY
Mary B. Bogardus, born abt 1825 ME
no children are shown
In 1880 they are found in Coldwater, Branch, MI
Various trees I’ve found conflict so I won’t repeat the information that I’ve found here. But based on what I have found I believe that the Mr and Mrs Bogardus mentioned in the letters are almost, not exactly, relatives of Sarah Ann Wisner Camfield, he being the grand-nephew of her aunt’s husband.
