Hi Everyone,
I missed this when it was first posted. Can't resist adding my gt. gt. grandfather.
Sorry, Silviaann, but my gt. gt. grandfather beats your's
by 14 years.

.
James Dickers d.o.b. 23 May 1796
Birth of last grandchild (that I know of), Leslie J. Dickers was registered in the Mar. Quarter 1922, over 125 years later!
James' first child was born in 1820 and his last child was born in 1877. A 57 year age gap between half siblings!
Children of his second marriage were born when he was
78 and 81.
Cheers,
Carmela
