This may be a diferent Edward Ackrill but here's my Akrill ancestors.
My GG Grandmother was Martha Akrill born 12.04.1857. Her parents were James Akrill b.1.11.1818 Kirton Lindsey and Charlotte Akrill (m. abt 1842). James Akrill's parents were Edward Akrill or Akerhill bap. 25.02.1787 Holton cum Beckering -1861 and Ann Miller b.1791 Corringham, Lincs. They married 21.6.1813. Holton is only about 6/7 miles from Legsby so it could be Edward gave on the census the town he grew up in rather than his place of birth. Edward Akerhill's parents were William and Ann Akerhill. It appears they have been known as Ackrill, Akrill and Akerhill. Best wishes, Raine
