In 1851 John and Ann are living at West Gate, Doncaster.
In 1861 they are living at Maltby.
In 1871 at Cumberland Street, Sheffield. (John is now a widower).
In 1851 Ann gives her place of birth as Gildingwells, Notts.
Gildingwells is roughly half way between Dinnington and Carlton in Lindrick.
Living with widowed John Lockwood senior in 1871 there is a Sarah Machin. I think she is the mother of John Lockwood born 1865.

I think this is the burial of the Ann Lockwood you found.
Ann Lockwood aged 40yrs,of Sandbeck, buried at Letwell 1 February 1863.
(Letwell is not far from Dinnington).
Henry Lockwood Machin, bap 30 Sep 1873 at St. Simon, Eyre St.
Mother - Sarah of 10 court Porter Street.
Is it possible that Ann Lockwood died after giving birth to John and that John was not baptised until the following year? The six year gap seem rather a long time between John baptised in 1864 and Henry Lockwood Machin born in 1870.
