A maternal haplogroup is a sub-population of people who share a maternal lineage.
L2a1 is a human mitochondrial DNA haplogroup. It is widely distributed in subSaharan Africa and among African Americans. L2 is the most common African lineage. The a1 subgroup of L2 is found in North Africa, Central Africa, and in East Africa. Other L2a1 groups are found in Ethiopia and a few in Syria.
All this tells is where ancient ancestors may have originated. It is of little to no help with your family genealogy. For that you need to trace the history of your family backward one generation at a time to find out who they were.
Please let me know if you have questions.
