Hi Listers Perhaps someone out there is familiar with the Muster Roll information of the War of 1812 for the USS Oneida. I have found 3 family ancestors on this Ship USS Oneida during the War. Under "Where Appeared" it states Sackets Harbor. Entry Day/Mo/Yr are stated. But, here are a couple columns that I do not understand. Under Rank Column what does O.S. stand for? Under another Column it states D, DD, or R what do they stand for? (I believe this stands for transfer or Discharge or something of that sort. Example #81 Owen McGrath Entry Date Feb 10th 1812 Rank shows O. S. Then D Date 8/21/1813 Then under Where or for what Reason it states Sylph Now I do understand that the schooner Sylph fought the rest of the War along side the USS Oneida. Would this R mean Re-signed ? if so then what is D and DD for? This is from pg 156 of the USS Oneida Muster Roll Another Entry for him appears on Pg 1 where he is #23 dated Oct 29 1811 prior to the War but on the USS Oneida in Sackets Harbor. Thanks for your help and excuse my lack of knowledge on these particular Muster Rolls (as I do not have the sheet telling me Abbrev. meanings. Pat R
