While I am not knowledgable about this subject, this is what is posted at my 23 & Me website relevant to:
You descend from a long line of women that can be traced back to eastern Africa over 150,000 years ago. These are the women of your maternal line, and your maternal haplogroup sheds light on their story.
Pamela, your maternal haplogroup is J1c3.
As our ancestors ventured out of eastern Africa, they branched off in diverse groups that crossed and recrossed the globe over tens of thousands of years. Some of their migrations can be traced through haplogroups, families of lineages that descend from a common ancestor. Your maternal haplogroup can reveal the path followed by the women of your maternal line.

If every person living today could trace his or her maternal line back over thousands of generations, all of our lines would meet at a single woman who lived in eastern Africa between 150,000 and 200,000 years ago. Though she was one of perhaps thousands of women alive at the time, only the diverse branches of her haplogroup have survived to today. The story of your maternal line begins with her.
Origin and Migrations of Haplogroup J1c3
Your maternal line stems from a branch of haplogroup J called J1c3. Haplogroup J1c3 is a relatively young branch of J that traces back to a woman who lived approximately 9,000 years ago. Her ancestors migrated into Europe from the Middle East as the Ice Age receded between 14,000 and 11,000 years ago. While J1c3 already existed in the west before the spread of agriculture, it likely expanded along with the farming populations as they moved west across the continent.
Today, J1c3 is found almost exclusively within Europe, and researchers speculate that the traces of J1c3 in the Middle East are due to eastward migrations of people much later in human history.
J1c3 is relatively common among 23andMe customers.
Today, you share your haplogroup with all the maternal-line descendants of the common ancestor of J1c3, including other 23andMe customers.
