Hawthorn, William

Rev. War research in attempt to prove military service for the William Hawthorn buried at Mt Pleasant:

PA Archives 3rd Series, Vol. 23, page 387:  PA Line, 1777-1780.   Misc. soldiers:
William Hathorn, Pvt., Capt. John Steele's Company, Sept. 1777.   ((Note spelling - 'Hathorn'))

PA Archives 3rd Series, Vol. 23, page 550:  PA Pensioners:
Hathorn, William - Pension April 3, 1819.  Died July 14, 1832, Goochland County VA.

This appears to possible be the same William 'Hathorn' who served in the 11th Rgmt. Pa Line.  The 11th was formed in the county of Philadelphia and counties nearby.
