Gary -- I don't have any info on your line, but have done extensive research on the early Wood families around the time of the Rev War.
Regarding the Wood Family Index, don't take it as gospel. However, it's a place to start. I descend from Abner Wood, b 1765, who is found in two places, each with different parents.
The census records should be fairly accurate, but not always. How about land records? Early history for the town they lived in?
