Apr 1670 A "youth" named Humphrey Davenport witnessed Staten Island deed. The 3 other "youths" were 13-14 years old. Colonial records of the City of New York.
Jul 1671 Humphrey1 divorced from Rachel. Has more than 1 child. Records of New Amsterdam
April 1684 Humphrey2 married Johanna Rosenkrans in Kingston and said he was "born the Barbados." Kingston RDC records
Oct 1697 Last evidence for Humphrey1 in New York. New York tax lists


For Humphrey2 to have been born in Barbados, he would have had to have been born between 1662 and 1665 or have been the son of someone other than Humphrey1.  Since all indications are that Humphrey2 was born in Barbados between 1656 and 1660, he is logically not the son of Humphrey1.

The idea that Humphrey2 is the son of Humphrey1 is not supported by tradition or historical evidence. It is the result of the proliferation of musings by recent "lumpers," -- those who liked to imagine that all Davenports are related -- and by the 1660 baptism of Humphrey in Barbados (who we now know died in 1662).

DNA Evidence

Many believe that William Davenport (b. 1666 CT) and Humphrey2 Davenport (b. abt. 1660 Barbados) are brothers, the sons of HumphreyDavenport. The descendants of William and Humphrey2 share an uncommon Y-DNA profile which shows that the two Davenports are not related on the male line to any other known Davenport family of England or the US. Not only are they not related to any other Davenports, their Y-DNA is almost unique and not closely related to many others that have been analyzed. They are clearly closely related.

The DNA analysis of the descendants of William and Humphrey2, however, cannot tell us if they are brothers, first cousins whose fathers went to Barbados together, or say, 6th cousins who just both happened to have a Barbados connection. There is enough difference between them (4-steps) that statistically, the odds of William and Humphrey2 being brothers is less than 10%. (Correct me if I am wrong, I'm not a scientist!) But thatís just probability and so cannot be used to prove anything.

The probability that two participants share a common ancestor when matching on "X" number of markers within the last "Y" generations.
