Hi Jannita, I don't see that anyone has answered yet. A SEP means that the baby was born last September and is therefore less than a year old. Other years' censuses might have written it as 8/12, or whenever the census was taken. -----Original Message----- From: Bill Weidenbach <[email protected]> To: [email protected] <[email protected]> Date: Tuesday, February 08, 2000 6:54 PM Subject: Re: [ILWASHIN] Question on 1880 census? Hi, Would any one know what SEP stands for on the 1880 census? It comes after the childs name, it says-Henry - White Male sep son Single. Would it stand for step-son? Thanks, Jannita
