Karen,
Here is the only info I have on William Nunn. He is the only Nunn shown in the reimental book. Of course there are often errors in the records.
He was in Company H of the 51st. He enlisted 7/2/61; medical discharge 7/24/62; tuberculosis of the right lung. 26 years old, 5' 10", light complexion,light hair, black eyes; a farmer.
There were 3 Handy's listed as well: Harrison H., Nathaniel, and Peter. All 3 were in company H as well.
Now for the 24th could that Captain Lybrook instead of Lynbrook? There were Lybrooks here in Patrick but no Lynbrooks.
