This is to provide information.Though I am not related to this line.I wanted to share this information.
I am related to James Coward and Miss Weaver.
However, in my search I have come across document "Immigrant Ships transcribers Guild"regarding the ship "Levent" it is a List of Manifest of all passengers taken aboard the ship Levent from Liverpool. It arrived from Liverpool to New York July 5, 1843.It contains a James Coward 25 year old male, Mary Coward 23 year old female, children George Coward age 2 Elizabeth Coward age 6, I also have a note that James's birth was 1818(this I figured given the records indicated)All are from Wales and are indicated as Farmers.They brought with them 3 boxes.
Anyone wishing the website where this is found, please email me and I will let you know.
