About us
The GIBBONS/FITZGIBBON (& other variants) Y-DNA Project was established 2002. Y-DNA-matching identifies distinct family lines/branches/groups via a significant proportion of 37-or-more STR markers on the Y chromosome; only 30 markers in common means there is not sufficient commonality to consider 2 persons a match having ancestors in common. Matching 36/37 markers is considered a Genetic Distance of one step at the y37 level. Matching 35/37, with a difference of 2, is considered a a Genetic Distance of two steps.
If your marker values are a close match to one of the family groups you are related to that family. If your DNA is significantly different from another individual you know that you do not share a common ancestor. A negative result trims the family tree. A positive result is very exciting and is a conformation of relatedness.
In Ireland, a royal FitzGibbon line was begun with Maurice FitzGibbon (about 1305-1357); great great grandson of Anglo-Norman Welsh Maurice FitzGerald (1100-1177). Maurice FitzGibbon was knighted "The White Knight" in the field by Edward III in 1333, immediately after the English defeat of Scottish forces at the Battle of Halidon Hill. The White Knight is one of three Hiberno-Norman hereditary knighthoods within Ireland dating from the medieval period; the other two knighthoods being Fitzgerald: Knight of Glin (also called the Black Knight), which has become dormant after 700 years (since the passing of the 29th Knight, September 2011), and Fitzgerald: Knight of Kerry (also called the Green Knight), which is held by Adrian FitzGerald, 6th Baronet, 24th Knight of Kerry.
