"Sandi Street:Research indicates that my side is related with the McGregors from the Jacobite uprising and Rob Rob Roy. But not sure if the McGregors became part of the clan because of a meeting of the clans men and a decision to make it so and not by marriage. I am not sure if there are any mixed blood lines. The DNA test sounds intriguing to me now."
The Grants (Grannd, from the Norman-French "le Grand," meaning "the big") are a Norman family introduced into the north of Scotland by the Bissets on the return of some of them from their exile of 1242. In England the Bissets and the Grants possessed adjoining lands in Nottinghamshire and were intermarried. In 1246 King Henry Ill of England granted Lowdham to Walter Byset till he should recover his lands in Scotland. The adjacent manor of East Bridgeford was then held by William le Grant, who had married Alfreda Byset, a Bisset heiress, They are first recorded in Scotland when Laurence and Robert Ie Grant appear as witnesses to a grant by the Bissets to Beauly Priory near Inverness in 1258. Later, as Sir Laurence le Grant, the former appears as Sheriff of Inverness, while Robert is recorded as holding land in nearby Nairnshire. As sheriffs of Inverness, the chiefs of the Grants became established in the Glenmoriston area around their center at Castle Urquhart on the northeastern shore of Loch Ness, and acquired blood-ties to the native-men of the district, who held themselves connected to the MacGregors, which may simply indicate their traditional connection to Argyle. In this connection it should be mentioned that the arms of the MacArthurs, formerly princes in Argyle till 1427, could be taken as a differenced version of the arms of the Grants as both color and the "Cross Moline" are standard marks of difference to show bloodrelationship. There did exist a famous Norman family of Grants in the early thirteenth century with the same armorial motto as the Scottish Grants:
"Stand Fast,"—Latin, Tenons Ferme. Nevertheless, the arms of the Grants, three golden antique crowns on red, may have been inherited at the time that the Grants settled in Scotland around 1258, hence the possible MacArthur connection (a similar inheritance of arms happened in the case of the Haldanes of Oleneagles).
In any case, since the Frasers quarter the Grant arms for their Highland inheritance (see above), they probably inherited Lovat ultimately from a Bisset heiress, but more immediately through a Grant heiress. Notwithstanding their growing clan following, the Grants did not gain a real foothold in the Highlands until 1434, when their then chief, Sir lain Grant, Sheriff of Inverness, acquired a vast district in Strathspey by marriage to the daughter and heiress of Gilbert of Glencairnie, the descendant of a younger son of the House of Strathearn (see Chapter VI). Afterwards they came to dominate Strathspey from Aviemore to Rothes.
