Margaret, thank you! It seems quite possible that James Hart on that list, from Kilmore Parish, Ballyloughan Townland, is Samuel Hart's brother, as Samuel was born about 1815, according to his grandson (Eli Hart, my grandfather). Eli Hart also said that Samuel's brother James Hart was born in 1818.
Can you verify what the date at the end of the name, 1833, indicates? Many thanks.
