Uncertain Existence
https://www.wikitree.com/wiki/Nunnally-75
No sources have been found for the birth or death of Richard Nunnally, his marriage to purported wife Elizabeth Wren [or Elam], or his children. Family trees online, and especially on ancestry.com, include this Richard with wife Elizabeth Wren and/or Elizabeth Elam in Henrico County, Virginia Colony. Children vary, usually including one or more of these: Richard, Daniel, Thomas Nunnally.
No evidence has been located for a marriage of Richard Nunnally to anyone named Elizabeth, or anyone else. No evidence has been presented for a connection to any children -- no will, deed, birth record, etc. Richard is usually said to have been born in Shropshire, England and immigrated to the Virginia Colony. An immigration record for a Richard Nunn is often cited, but again there is no evidence that this Richard's name was ever given as "Nunn" or that his father was named "Nunn."
For more information on the lack of evidence, see the Nunnally Family on the Shropshire Family History Society website. http://www.sfhs.org.uk/forum/nunnally-family
