In Samuel Warren Dike's biography of Capt. Anthony Dike, it mentioned that a John Dike and his father, Thomas Dike, (both in England) had business dealings with the colonies in the West Indies - this would have been around 1637. It also mentioned that John Dike had four brothers - Robert, Thomas, William and Richard. The article went on to say that the relationship between Anthony Dike and this John Dike was unknown.
Also, according to the Virginia Historical Magazine, The New Government for Virginia, 1624, Pages 38-40:On July 15, 1624, in Westminster, England, a Commission was established by King James to take in consideration a new form of government for Virginia.A member of that Commission was John Dike. This could be the same John Dike as mentioned above, or maybe related(??).
If anyone has any information on John Dike and/or his family, I would appreciate hearing from you.
