Hello
The tithe maps for Kidderminster in 1842 are on the Worcestershire Archives website.
I found it really difficult to work out how to search the map
At the top you seem to need to click on tithes in the Inclosures,tithes ,estates choices
then in the box at the bottom name William Collins and tithes.
It seems to bring up one entry on Comberton Hill Kidderminster just above the railway station
Tithe 1s 6d . Size 0,0,33.
He owned and occupied it.
I can't really get a grip of it but it is there.
