Did you check www.manxie.freeservers.com/custom2.html which I mentioned on the previous discussion on the Maddrells a couple of weeks? There is also a Harrison line with a Maddrell and another Callow connection on this site. I tried to e-mail the author Adie Jack recently,but so far haven't received a a reply.
The inventory on Margaret Maddrell's administration is 2 and a half pages long and has been transcribed. It has a lot of unusual words so I included a glossary. Could send you a copy Donna, by e-mail
