Teynham.
The origin of the name, Tenham, seems difficult to determine. The earlier charters (798 to 801) and Domesday Monachorum mention it as Teneham, Taenham, Tenaham and Tenham, and it is still pronounced ten ham with an accent on the first syllable. In Domesday Book the name occurs as “Therham” (probably a clerical error).
In any case, the name is ancient and handed down unchanged in pronunciation. The “y” in “Teynham” was apparently added by the Roper family.
Your first puzzle is a wordsearch, a pic of it is below. And you only need to find one word, "Teynham" but 40 times!
After that you will have some "teynham" letters left, and hopefully if you count correctly you will have a sequencial range of numbers, although maybe not all in the correct numerical order.
