Rickman, Weaver, Nickens, etc.
The Library of Virginia has an excellent on-line source for chancery records. They contain far fewer cases than one finds in regular court records, but there is far more information on those few cases since they include all the depositions taken a the case.
Under Henry County there is a case where a Rickman is first identified as mixed-race. There is a case in Lancaster County that identifies Elijah Weaver's mother as Ann Kelly Weaver and a case that identifies some of the descendants of Amos Nickens.
There is also a Lancaster County case against Spencer Weaver and Billy Weaver who took a loan in Norfolk County for $110 to pay for a vessel. Billy was not found in the county when the case came to trial (and does not appear in tax records), so perhaps that is one of the connections between the Norfolk and Lancaster county Weavers. Billy was said to have been paid $30 for travelling to Charlotte as a mariner and said to have been Spencer's brother.
Good information there from Bedford County on Zachariah Goff who worked for Richard Moss and whose wife was Betsy Moss.
A search for Dungee also gets good results.
It is a work in progress. Not all counties are included and only some records have been digitized.
