minor correction - the site is not mine - it is given by www.isle-of-man.com (Andrew is their guru) - Sue and I (with another helper now they are back online) do much of the spam removal that keeps it ticking along but the site is only as good as the contributors.
Peel FHSoc library is never going to match the Museum or General Registry (the only additional resources it can offer are the various submitted family trees, all films are duplicates of those in the museum) - the people manning it are all unpaid volunteers and from my experience have all been very helpful - the limited opening hours make it not very attractive for me tho I used to often drop into the old library on Sat afternoons to check up various small items.
