Y-DNA STR Markers - A Case Study

To follow is a scenario of how Y-DNA STR marker testing can help Mr. Brown dig up his ancestral roots:

Mr. Brown is interested in researching his roots and is expanding his ancestral search. Mr. Brown has several male relatives which share his surname. The oldest living male member of his Brown line is his grand-uncle who is 89 years old.

Mr. Brown begins by testing himself, his male cousin (his dad's brother's son), and his grand-uncle. Because of the age of his grand-uncle, it is important for him to test the senior Mr. Brown right away because his grand-uncle is physically very frail and may not be available for testing in a few years.

Important Tip: It is always important to try to have the oldest male members of your family line tested as soon as possible to capture important information before it becomes too late.
