Please remember to use variant spellings, partial spellings, etc. The transcriptionists are not the expert on the spellings, nor do they make guesses on what they think the name should be, so the names you find here are the best that could be done from the document. This spelling may not be correct or the document may be difficult to read so the correct spelling is not made. If you find your person and know the proper spelling, please contact me and I would be happy to add the name to the index.
