My wife's brother tested recently with FTDNA and discovered they carry an A mtdna. They have lots of matches in Puerto Rico and some in Mexico. I've seen speculation that A lineages in Puerto Rico are not Taino but from a people who came there either from the southeast USA or Yucatan peninsula far earlier than the Taino. My wife has no known connection to Puerto Rico. Can any of you fine Worldfamilies.net folks shed any further illumination on the subject?

Wikipedia Haplogroup A (mt)
Origin

Haplogroup A is believed to have arisen in Asia some 30,000-50,000 years before present. Its ancestral haplogroup was Haplogroup N.
Its highest frequencies are among Indigenous peoples of the Americas, its largest overall population is in East Asia, and its greatest variety (which suggests its origin point) is in East Siberia. Thus, it might have originated in and spread from the Far East or Central Asia.[2]
[edit]Distribution

Its subgroup A1 is found in northern and central Asia, while its subgroup A2 is found in Siberia and is also one of five mtDNA haplogroups found in the indigenous peoples of the Americas, the others being B, C, D, and X.[2]
Haplogroup A is the most common haplogroup among the Chukchis, Eskimos, Na-Denes, and many Amerind ethnic groups of North and Central America. Approximately 8% to 15% of Koreans belong to haplogroup A.[3][4] Approximately 7% of the Japanese belong to haplogroup A (mostly A4 and A5).[5] 2% of Turkish people belong to haplogroup A.[6]
____
 All Indigenous Amerindian mtDNA can be traced back to five haplogroups, A, B, C, D and X.[52] More specifically, Indigenous Amerindian mtDNA belongs to sub-haplogroups that are unique to the Americas and not found in Asia or Europe: A2, B2, C1, D1, and X2a (with minor groups C4c, D2, D3, and D4h3).[51] This suggests that 95% of Indigenous Amerindian mtDNA is descended from a minimal genetic founding female population, comprising sub-haplogroups A2, B2, C1b, C1c, C1d, and D1.[52] The remaining 5% is composed of the X2a, D2, D3, C4, and D4h3 sub-haplogroups.[51][52][/i]

Therefore for a total of 591 ameridian haplogroups , 170  are haplogroup A (28,7% of the total.

See A2 in http://phylotree.org/tree/subtree_N.htm
A discussion about mutations in haplogroup A2 can be found into
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1914796/pdf/ajhg00023-0194.pdf

with the mutations of your parent, you can compare with the A2 tree in
http://www.plosone.org/article/info:doi%2F10.1371%2Fjournal.pone.0001764, but there is certainly a specialist of Amerindian mtdna  who can consult by mail.

Maybe, James Lick will be able to answer you or, at least, help you to find a specialist :
