I Johnson, Thomas, born at Selby in Yorkshire ; a Lieut. Colonel in the 

 royal army during the civil wars, created M. D. Oxon, in 1643, in considera- 

 tion of his loyalty and learning j killed in 1644, " at which time his worth did 

 justly challenge funeral tears ; being then no less eminent in the garrison for his 

 valour and conduct as a soldier, than famous through the kingdom for his excellen- 

 cy as an herbalist and Physician." See Pultcney's Sketches, i. p. 128. &c.
