I was particularly interested in the area stretching between south Belfast and Killyleagh, as this is where our great-great grandparents, Joseph Stewart and Elizabeth Madine, had most of their children in the 1860's and 1870's, before their permanent move south to Dublin.
I had already discounted a Joseph Stewart of Annaclone from my search, since he already had a son named Joseph, and you can't have two! I also eliminated a Joseph Stewart of Carnamuck, Castlereagh, as he was far too young (according to his headstone) to be the father of our great-great grandfather.
I thought I might discover a Joseph Stewart farming near Killyleagh, since two of the sons of our Joseph Stewart, married two of the Madine sisters of Killyleagh - I found no mention of a Joseph in this area however.
Anyway, the following list is a survey of Stewarts farming in North Co.Down in the 1830's and it may be of some use to somebody.
