Hi Mary,
Thanks for the info about the MNH library. Did the folder & tree which they brought you, entitled Kerruish-Ballafayle & other Maughold Kerruishes, include the family which you are looking for? The one described by Sandra?
I've looked up what Philip Allen wrote about the copies of CR's trees which he bought there in late 2006. He said he looked at two boxes containing a lot of notes for her Maughold and Ramsey books, and various talks, and a quantity of family trees. The MM staff did the photocopying, and limited him to 100 sheets. He thought the trees might be the same as the copies at the FHS library.
The IoM FHS said in the Journal that they had received three folders of family trees by Constance Radcliffe. Philip found that these were photocopies, all Maughold families, copied onto A3 card. At the time the A3 copier wasn't working which was why he went on to the MM.
If the MNH library didn't give you the boxes it might be easier to look at the three folders at Peel? - That's if you haven't already found a tree for your ones?
