All very interesting, John, and thanks for the name research...
I think that the March quarter 1852 birth registration looks spot on now. Interesting that when I sent away for the birth certificate for one of Ellen JOEL's sons (became THATCHER after her marriage in 1898), even though he was born in late August, his parents took the whole 6 weeks to register the birth, which then appeared in the December quarter.
What I'm saying is, can't discount the fact that Henry HOUSE might actually have been born late in 1851, with his birth registered early in 1852.
Things getting considerably clearer, though,
