John,
That does appear to be a partial Dragoon return for 1st Quarter 1834!
I would certainly love to see more of it and any others that may be filed in the same location. Do you know if the returns show accoutrements as well as arms? If so they may well answer some perplexing questions.

I am familiar with Will's very fine site but thank you for taking the time and trouble to link it.

As for the accent on my name - I don't mind at all if it is left off. It took my son to find it for me on my computer...If you wish to use it why not copy and paste this:

I'm very grateful for your help in this - dragoon information is very hard to come by.
