I may have replied in an eaerlier post, but there is a Flack message board at the website
www.flackgenealogy.co.uk and the lady who co-runs the site with me is a registered member of the 'Guild of One-name-studies'. There is a huge Flack database onsite and the lady genealogist (Denise) has a huge collection of Flack records she is willing to share with anyone who asks.
I also have some Flack documents and photos at
www.jamesflack.com - again - I'm willng to share with anyone who asks.
I'm also obviously always looking for new flack families to add the the searchable database - it benefits every researcher and of course its all free.
