Hi, Just reviewing ancestry board on the Sheridan. Did you have any luck with your questions on the Sheridan. I have never found a picture of the Sheridan but I do have a copy of the ship building license for the sheridan and it gives the date of construction, location and size.
My relatives came to New YOrk harbor from England. landing in New York in August, 1849.
I have a copy of the ship manifest for that voyage also.
I have not worked on the Sheridan information for quite some time as I, like everyone else, had trouble finding data on the Sheridan.
I found no pictures but have a good description of the size.
If your still looking for info and I can be of help, I will be glad to assist as best I can,
