If by information you mean who his parents were or who his descendants were I believe you will find that while some people attach him to the Kelvedon Wright family and some people claim he has descendants including the Richard Wright of Plymouth who married Hester Cooke, none of those claims are currently accepted by authorities.
I have been interested in this question for some years because it had been a tradition in my family that Richard Wright was the son of William. However, there is no evidence whatever, to my knowledge, that William had any children and every reason to think he did not. Neither is there any evidence, to my knowledge, that connects him to any Wright family.
I know that there are online trees and trees on those notorious CDs which make claims for William, and even some published works such as _Saints and Strangers_ say Richard is his son, but I have never seen any claim that was backed up by actual records, and every time I have inquired about the source of a person's information I have been told that it came from some online tree, someplace that has been forgotten, some secondary source with no documentation, etc. So far no one has been able to show me any evidence that links William either to descendants or ancestors. I would very much like to see some, but I feel it is very likely there simply is none.
