Many thanks Walter.I will have a look at Marge Reid's site and also at the LDS records.
I think I might have found a link in the chain - I am going to Inverness on Wednesday to have a look at some records on the MacDonell of Glengarry family - I was having a look at the Historical Manuscripts Commission site and low and behold, they have some info on Glengarry!Fingers crossed - there might just be something.
What branch of the MacDonalds are you from? My e-mail is firstname.lastname@example.org.
Once again many thanks Walter and greeting from rain soaked and wind blown Shetland. Fiona
