Another bookplate of interest at eBay, that of The Hon’ble Allexander Grantt, younger of that ilk. Anthony Pincott very kindly sent me a scanned copy from his collection:
A look through Burke’s Landed Gentry The Kingdom In Scotland reveals that Alexander was the son of Ludovic Grant, 1st of Grant:
“LUDOVIC GRANT, 8th of Freuchie and 1st of Grant, who obtained a charter, 28
Feb. 1694, erecting his lands into the regality of Grant, m. 1stly (contract 21 Dec.
1671), Janet (d. 1697), only child of Alexander Brodie, of Lethen (see that family).
He m. 2ndly (contract 1 March 1701), Jean (d. 31 Jan. 1734), widow of (1)
Walter, 3rd son of Walter Dundas of Dundas, and (2) Richard Lockhart, of Lee,
dau. of Sir Patrick Houstoun, Bt., of Houstoun (see BURKE’s Extinct & Dormant
Baronetcies). He was bur. 19 Nov. 1714.
ALEXANDER GRANT, 2nd of Grant, Brig.-Gen. in the Army, Lord Lieut. cos.
Inverness and Banff, M.P. for co. Inverness 1702-07 in the Scots Parliament, and
sat in the first five Parliaments of Great Britain, m. 1stly, 3 Dec. 1698, Elizabeth
(d. 22 April 1708), dau. of James, Lord Doune, eldest son of 5th Earl of Moray
(see that title). He m. 2ndly, 7 April 1709, Anne, Maid of Honour to Queen Anne
(d. 10 June 1717), dau. of Rt. Hon. John Smith, Speaker of the House of
Commons, and d.s.p.s. 19 Aug. 1719, when he was s. by his brother,
JAMES GRANT, of Pluscardine, afterwards Sir James Colquhoun, 6th Bt., of
Luss, and subsequently SIR JAMES GRANT OF GRANT, MP Inverness and
Elgin 1722–47, b. 28 July 1679, m. 29 Jan. 1702, Anne, only dau. and sole
heiress of Sir Humphrey Colquhoun, 5th Bt., of Luss (see that title), and
assumed the name of COLQUHOUN 1706. He s. his father-in-law 1718 as 6th
Bt. of Luss (see COLQUHOUN lineage above), and in the followng year s. his
brother in the Grant estates, when he resumed the name of GRANT. She d. 25
June 1724, having had issue, with eight daus., six sons.”
From the above we can deduce that the bookplate dates from between 1694, when the lands were erected into the regality of Grant, and the death of his father in 1714. Anthony Pincott advised that the bookplate is nearer 1705-1710.
The power of Google also reveals that Alexander Grant was one of those who voted in favour of the Union with England in 1707.
