Who I am: Ancestry.com and Geographic Granularity

This is one in a series of posts on the search for my biological family.

So, this is really cool. AncestryDNA just released another update to their analysis which provides considerable more geographic granularity. In my case, they've broken down Ireland into 92 (!) smaller regions, and placed my origins into North Roscommon, which is a smaller area in County Roscommon centered around the small town of Elphin. Ancestry will then link you to DNA matches who are also from that small region. In my case, there are 124 matches (and several that match my birth surname). Add to this the fact that a number of historical records show that my ancestral family is from this very region.
