Hi. Killick was my maiden name.
Have you checked with The Killick Society, and/or the Guild of One Name Studies?
The Goons have a lot of Killick research online, which includes loads of births, marriages, deaths, probates etc
The contact for the Killick Society is also on the Goons site. It has been in existence for about 30 years and has loads of data.
The Killick roots were in Surrey around Nutfield and Blechingley, spreading over the county boundaries into north Sussex and west Kent.
Sure I have Tadworth etc in my files somewhere but can't find for the moment. Will write again if and when I have found them. There are a few very large branches of the family, and many small ones we have not fitted together.
(I am a newcomer to Rootschat and finding it a struggle to negotiate the site. Hope I can find my way to your enquiry again!!)
