It's
worth trying both searches - you may get different results
Google
Custom Search
You can also use Google itself to search this site... What you need to do is type:
/FamilyHistory/ william site:http://www.thekemps.org.uk
into the Google Search bar, replace the william with the word or phrase you want to search for, remembering to ensure there is a space either side of it, and see what you get back!
