You know, I am beginning at last to have suspicions about the "Newcastle" statement. This statement was strictly hearsay, reported during a reunion of Clan Macrae and documented in the clan's newsletter.
The evidence gives Leeds ten times for every Newcastle statement, where Murdoch Maclean is concerned.
Following the post from the great-great-granddaughter -- thank you, Melinda!! -- I did another search, and as a result I believe I have found where Murdoch Maclean and his wife are buried, with the info engraved on the headstone. It says:
Murdoch Maclean 1885 - 1956
Jeanne Maclean (identified as Murdoch's wife) 1888 - 1979 (long-lived!)
