In looking through my notes, i find Rebecca listed as 29 on the 1850 census(but i haven't looked at the actual image, so either might be correct). I also have a note that she is listed as 42 in 1860, but would have to verify with images and don't have them at hand. Rebecca eventually married (1855) William Ham who was the widower of her sister Massa(died 1852). William and Massa had a son named John Avery(I have him listed as 17 on the census) who might well have been living with his aunt and grandparents. I can't figure out the Ann however. The Staggs had another daughter, Melissa, who died about 1846. Once again these dates are based on on-line census transcriptions since I don't yet have access to the images.
