Ok folks, I've cracked it.
James Ives & Mary Ives(nee.Channer), married at Chesham, Bucks in 1819.
4 children baptised @ Chesham(of Chartridge).
Mary - 1819. Shows in 1851 & 1861 census, born Chesham.
Eli - 1821. Still a bit unsure of his marriage and census returns.
Elizabeth** - 1822. Marries James PARKER(b1820. Bledlow) in Holy Trinity Church, Bledlow, Bucks. in 1847. (Fathers name - James IVES, labourer).
Joseph - 1823. Married Ann Harman/Harmon in 1850 P.Risborough......and then vanishes after 1851.
And finally John IVES, baptised 1826 @ Stoke Mandeville. (My chap).
**Elizabeth Parker(nee.Ives) provides the best clues.In Bledlow in 1841 under Elizabeth HIVES.
In 1851 her p.o.b is given as Chesham.
In 1861 her p.o.b is given as Stoke.(Mandeville ??).
In 1871 her p.o.b is given as Chasterage(Chartridge), Buckinghamshire.
In 1871 her p.o.b is given as Chesham.
The confusion of all these childrens p.o.b's, would be their mothers death in 1828 in Stoke Mandeville, and then being scattered around Bledlow, and Bledlow Ridge.
James IVES 1791 (Son of James Ives & Mary Wooster), dies in the Union Workhouse @ Amersham, aged 70, of Shaking palsy(Parkinsons disease). Buried - 7 Sep 1860 @ Gt. Missenden.
Still a few I's to dot, and T's to cross yet.
Steve.
