Y-DNA Testing

A definitive scientific advance in Y-DNA testing, that had been available to the public since 2013, ^[1] finally intervened in 2015, in the form of next-generation-sequencing (NGS) Y-SNP tests of Y-descendants of:

The surname spelling Goodridge remained among Y-descendants of William-1 Goodridge of Watertown, Massachusetts until the early 1800s when, in most cases, the original surname spelling Goodrich was restored.

William Goodrich III/Goodridge of Watertown, MA - G50, ^[2]

Thomas Goodrich of Old Rappahannock, VA - G62, ^[3]

William Goodrich of Wethersfield, CT - G18 ^[4]

The results of the testing showed that:

1) G62, G50 and G18 all shared the Y-SNP mutation E-L1019.

2) G50 and G18 shared the Y-SNP mutation E-FGC44079; G62 did not.

3) There were no other Y-SNPs shared by any pair of G62, G50 and G18 that were not shared by the third kit.

Therefore, since:

A) G62 descends from: Thomas-1 Goodrich of VA (John, Adam, Robert). ^[5]

B) G18 descends from: William-1 Goodrich of CT ( John, William I, Robert). ^[6]

C) G50 is more closely related to G18 (they share E-FGC44079) than to G62 (they do not share E-FGC44079).

The following must be true:

D) G50 and G18 must be co-Y-descendants of William Goodrich of Hessett. ^[7]

E) The E-L1019 mutation must have been present in Robert Goodrich of Felsham (~1505-1570); the apparent most-recent-common-Y-ancestor of G62, G50 and G18.

F) The E-FGC44079 mutation must have occurred after eldest son Adam Goodrich came into existence in ~1536 and started his own separate Y-line, so that the E-FGC44079 Y-SNP mutation would not be shared by Adam Goodrich Y-descendant G62, while the Y-lines of G50 and G18 were together through Robert Goodrich (~1536-1544), and then through William Goodrich I of Hessett (~1545-1579).

G) The E-FGC44079 mutation must have occurred before William Goodrich II of Hessett came into existence in 1580 and started his own Y-line, so that the E-FGC44079 Y-SNP mutation would be shared by William Goodrich I of Hessett co-Y-descendants G50 and G18; then after 1579, the Y-line of his younger brother John Goodrich, who came into existence ~1587, was carried by William Goodrich I of Hessett from 1580-~1586, and then by John Goodrich from ~1587 onward.

H) The only known Y-descendant possibility among the Y-descendants of Robert Goodrich of Felsham that enables C) is the son of William Goodrich II of Hessett and Barbara Cole; "______ Goodrich", baptized 11 Jun 1609 at Hessett and likely named William Goodrich III of Hessett afterward, since the family tradition was to name the eldest son after the paternal grandfather: William Goodrich I of Hessett. ^[8]

I) G50 therefore descends from: William Goodrich III/Goodridge (William II, William I, Robert). ^[9]
