I agree that "removed" (ie from the parish) is the most likely interpretation, though temporary removal may have been an excuse rather than a reason.
In the 1811 census report (Preliminary Observations p xxiii) it was noted that difficulties arose in relation to records of baptisms:
"... for the Canon ordaining Registers applies to Christenings, without further explanation; and this word is usually understood to mean Publick Baptism only. The practice of the Clergy is not uniform on this point; and it appears from the Remarks subjoined to many of the Parish-Register Returns, that the Registry of Private Baptisms is denied in many places, from a conscientious desire thereby to induce persons to cause their Children to be publickly received into the Congregation... Publick Baptism is sometimes prevented ... by an unwillingness or inability in the Parents to incur the expence ..."
As a general comment, the parish registers for Winteringham seem to be exceptionally good. The parish was fortunate in having such a conscientious curate who evidently had the general practice of both baptising children privately soon after birth (lest they should die unbaptised) and recording that baptism. Some other clergymen either refused private baptisms or, as indicated above, failed to record them. Two entries before Luke Dixon there is a record of Hannah Glover: born 15 January 1805, baptised, probably at her parents' home, 17 January but never presented in church, because she died on 28 March. In some parishes she would probably have gone unrecorded.
