I have since found out that my great grandfather, James Illsley, was born in 1871 in Stow Bardolph, Norfolk. His father was James Illsley born in about 1831 in Mistley, Essex. His father was William Carter Illsley, born in about 1803 in Melbourne, Derbyshire. There are no other Illsley's in Norfolk and Essex other than my family in the 1800's so I know that Derbyshire is where the family originated. We may still have a connection, let me know if you see something that connects us.
