Recent research has confirmed that their daughter Anna Maria Weatherwax (Witherwax) married Martin Edmund Vosburgh on 24 Feb 1842 at St. Johns Lutheran Church. Anna and Martin would have three known children:
1. Margaret O. Vosburgh 1845-1894
2. Franklin Vosburgh 1851-1914
3. Charles Vosburgh 1860-?
Anna M. Weatherwax and all children are mentioned in her husbands Will which was probated on 29 Feb 1872 Dutchess co. Will extracts.
His tombstone indicates a date of death for Martin Vosburgh of 5 Jul 1870, but that appears to be in error since he appears on the 22 Jul 1870 USC for Stanford,Dutchess co NY, with all family members matching!.
After receiving comments from Renee Zamora I did check the Enumrator instructions for USC1870. Clearly there it states that any household member who died between June 1, 1870 and the date of enumeration of the family must be listed in column 3 with other family members. So it now appears that the Tombstone date of death is correct.
