STR is an ancronym for Short Tandem Repeat. The human male Y-chromosome is repleat with areas are specific locations where nucleotides are found in repeating patterns. Human DNA testing has shown that these repeating patterns remain fairly constant across family lines. Short tandem repeats are a series of named markers where there is a known count of the repeating nulcleotide . A pattern like TATATATATA, where TA is the pattern, would have a count of 5 because it is repeated 5 times. A "difference" occurs where two closely related males show differing count values, one might have 5 repeated patterns while the other 6 repeated patterns. Genetic genealogists look for patterns in the STR differences that might also determine uniqueness in family lines of descent.


The following table shows the Short Tandem Repeat markers useful for providing additional means of differentiating between the various Mattingly-Matney lineages.

The value of STR marker Y-Gata-A10 can be used to identify whether a male descends from Thomas Mattingly II or his younger brother, Cesar "Cezar" Mattingly.

Y-Gata-A10 = 13: Descendants of Cesar "Cezar" Mattingly.
Y-Gata-A10 = 14: Descendants of Thomas Mattingly II.
