Manypenny, George
I'm not a Manypenny or Monypenny researcher but found this name in some records of veterans of the War With Mexico, 1846-48:
GEORGE MANYPENNY, Pennsylvania, filed for pension for war service on 02 Feb 1888, for his service in Howe's Co. 2nd Pennsylvania Dragoons, died 29 Oct 1916, Philadelphia.
I hope this helps someone.
