Hello
I notice you are looking for Tidcombe in Somerset, I am researching Titcomb the most common variant in Oxfordshire, Berkshire and Wiltshire. I have not looked at Somerset yet. I am forever searching for the birth/baptism/marriage of Edward Titcomb and Hester in the late 1700's so far with no luck!All their children were baptised at Enstone in Oxfordshire.
I'd be happy to share any info I have if you're interested.
