I am searching for the parents/siblings of my gggrandfather James Briggs, b.~1825. His middle initial may be "H". He married in 1848 in New Orleans, LA. He and his wife, Augusta and 2 children, Henry and Catherine, were listed in the 1860 New Orleans census, and domicile addresses through 1866 are available. Ireland was listed on the census record as his place of birth. His handwritten marriage certificate (in German) stated he came to Louisiana via "Nofig St. Virgin". I suspect this could refer to Norfolk - Virginia or UK. Does this connect with your Briggs family?
