Family link to Sir Richard Grenville.

This is from Meriel's side of the family, rather than the Morgans.

This is a section of the Sharp Family Tree, taken from Gloucestershire County Records (part of National Archive). Document is from Browne/Murray-Browne family records (ref number D6919/8/1). It is more clear in this image.

This section of the family tree shows Sir Richard Grenville (they spell it Granville) and his wife Mary, their son Sir Barnard Grenville, grandson Sir Basil Grenville, and their connection to the Sharp family through the wife of Thomas Sharp, Judith Wheeler. Thomas Sharp is the father of famous abolitionist Granville Sharp.

Sir Richard Grenville (the link goes to a excerp from The Dictionary of National Biography) was a famous tudor rear-admiral immortalised by Tennyson in the poem The Revenge. Meriel's family is connected to the Sharps through Thomas Sharp's great-grandfather James Sharp (as described in this post).
