I have had experience in reading birth, marriage, and death records, etc. in the Cayman Islands and doing my own transcriptions of the handwriting. In many cases, I can discern the difference between an L and an S.
You didn't, however, attempt to answer my question. Was her LNAB Morgan as the LDS family trees show? I've not found the 1842 marriage record and no baptismal records for her. Her birthplace seems to have been in Florida, not Georgia as one ancestry.com family tree shows.
