My ggg grandfather was Francis Garrod, his family were located in east Lincolnshire (near Skegness) at least as far back as the mid-1700s. His father was also Francis, perhaps the reason they are so difficult to track down is that I have seen the family listed as Garrod, Garrad (which is the spelling now used), Garradd, the list goes on! It might be worth looking under an alternative spelling if you are looking for a relative, I would be happy to exchange info if it is of any use to anyone.
