Henry Jefferies, born in Sible Hedingham, married Martha Atkin from Mavis Enderby in Lincolnshire in 1870 and they moved to Streatham, living first in the same road as his brother Peter. Henry was a house painter and is said to have died from lead poisoning at the age of 49 in 1892. He is buried in the Norwood Cemetery.

His eldest son, Jonathan Henry Jefferies, went to the USA in 1888 and settled in Florida where he became a horticulturalist with the Florida Dept. of Agriculture in the citrus industry. He married Rose Alice Smith who was the daughter of Benjamin Smith who was born in Sible Hedingham, Essex as had Jonathan's father Henry.  This suggests that Jonathan had some contact with the Smith family that encouraged him to emmigrate.

His brother, George Atkin Jefferies followed him in 1891 after receiving a letter from his brother and became a meat merchant and wholesale grocery merchant in Jacksonville, Florida.  He married Sarah Louise Hind whose father Thomas came from Worksop in Nottinghamshire.

On their father Henry's death in 1892 Henry's widow Martha and their four daughters all emigrated to Florida on the 28th November 1892.  Daughters Jane, Martha and Hannah all married and all of Henry and Martha's descendants are identified on the person pages by a green tree symbol.
