ALL PROFILES ARE FROM B.M.D. OFFICIAL SOURCES AND TEXT (EARLIER WHEREVER POSSIBLE)

Here is an old (forgotten) book, which is very interesting for anyone starting to research their family tree in the mid 18th century, with Scottish connections:

"The Memoirs of a Highland Lady", by Elizabeth Grant (b.1797,Edinburgh), the well known diarist,
and daughter of Sir John Grant of Rothiemurchus. "Uncle Leitch" is John Leitch Esq. of Kilmardinny, and Aunt Leitch is "Elizabeth Ironside" of Houghton le Spring.

The original Leitch/Leche researched eight years ago, is now held on a private server, to maintain the accuracy and integrity of the tree.
Due to the mis-translation “Lache” is also included in the family of “Leche” surname variations.

My new book (First Edition) is finally ready, after many years of research, and has now been published, Dec. 2020, and contains the results of the research into the Leche/Leitch family since the Norman Conquest of England (1066).

This work builds on an earlier work by:

Professor Major Archibald Leitch, (1878-1931), Pathologist, RAMC (TF) Director Royal Cancer Research Institute.
