This is a confusing family to be sure, but JJ and I were on the right track in trying to sort out the occupation problem.
For example, Ann Elizabeth Hill's baptism (1830?*) shows her parents as JOHN and Mary Hill, of New Castle St., JOHN being a coffee roaster.
Her marriage in 1859 to Henry Weaver puts her father as "Liflett" Hill, a coffee roaster.
John Lifelet Hill, assumably Ann's brother: his baptism gives this:
May 26, 1833 John Lifelet Hill, son of Lifelet and Mary, Crispin st, coffee roaster
His marriage states his father was a coffee roaster.
I cannot find a baptism for Ann's brother Joseph, but his marriage also states father was a coffee roaster.
The 1841 census shows bricklayer for Lifelet Hill.
The 1848 death for Lifelet Hill shows an address in Mile End New Town, occupation BRICKLAYER, and wife Mary Ann. EDIT: occupation is bricklayer's labourer.
I really think a good look is needed for Eliphalet's brother John, b 1803, to see if he may have had a middle name of Lifelet, and a coffee roaster, OR his father, John (did he remarry?) and that for whatever reason, Eliphalet was raising his children.
There is also a Mary ANN Hill, widow, remarrying in 1850, living on Church St, Shoreditch that should be ruled in or out.
* This baptismal book has the years scattered all over the place, the transcription says 1830, which could be right, but very hard to tell from the actual image.
