1629 Margaret Dodding by follower of Gheeraerts (Roy Precious Antiques and Fine Art)
MutualArt.com states the Gheeraerts follower is Sir William Segar. An article in Wikipedia mentioned a member of the Dodding family, George, as a "zealous Roundhead." Margaret was his relative, but I cannot find anything else about her.
