There's a site with a lot of information for Wing, but it's down now for maintenance.
http://wing-ops.org.uk/But there are archived copies in the Way-back Machine:
https://web.archive.org/web/20190102184554/http://wing-ops.org.uk/There are some notes that explain the gaps in the late 17th century:
Baptisms: 5 Jul 1546 to 7 Sept 1749
“carelessly recorded” from 1685 to 1688
1646 to 1663 not entered until 1663
entries missing or defective in 1558 to 1560 & 1645
Marriages: missing entries from 8 Oct 1684 to 2 May 1695
1646 to 1663 not entered until 1663
entries missing or defective in 1558 to 1560 & 1645
For the future, I could have a look at manorial court rolls the
next time I go to Aylesbury. Possibly sometime this year.
