The only thing I could find was WFT Volume 147, Tree 730. The info on Avery Brown is very skimpy.
Date born: WFT Est. 1800-1845
Died: WFT Est. 1825-1923
Married Angeline Turner WFT Est. 1825-1879
Angeline was born: WFT Est. 1807-1847
Died: WFT Est. 1825-1929
That's it - no parents or children.
Sorry I couldn't be of more help.
