potentially they may have only been up there a few months, with alfred and jean both registered in south stoneham with about 18 months gap, then they are unlikely to have had a child inbetween. Sorry but i thought jean was bn later than that.
looking at that southampton death now in 1829 for A A Hollis, aged 43, worryingly that does tie in with the age on the census for the southampton bn alfred hollis. will have a look at the papers later for a death notice.
