I also descend from Jonathan Griffey and his wife Agnes.There are several books of which you may know: History of Pocahontas Co., WV, by W.T. Price (1901) pgs 381-38(?); Hist. of Ritchie Co., WV (1911) Lowther pgs 414-416; Hist of WV by Amer. Hist. Soc. (1923) Vol III pgs 437-616; Some info given on Wm. Griffee Brown, Source Hist. Vol. II pg 168 & 387. While I'm aware of these books I have not been able to locate them to gain their information.If you know where I might find them or would care to share any history on Jonathan, the immigrant, I would appreciate it.I have a DAR application stating he was b in Switzerland & came here w/Lafayette who also served at Valley Forge.However that org. has no record of soldiers other than Americans.
