The Government of Cromwell won Iain Mor's admiration for the prosperity it brought Scotland but this soured his relationship with Airlie. On the restoration of Charles II in 1660, he found himself in trouble with parliament, who fined him heavily and at Airlie's instigation a law suit decreed that the Canlochan Forest, part of the Forter estate, belonged to the latter. This Iain Mor refused to recognise, continuing to pasture his cattle on the disputed land which Airlie had leased to Robert Farquharson of Broughdearg.
Broughdearg was Iain Mor's cousin but the dispute over the forest led to a bitter feud culminating in a skirmish at Drumgley, just west of Forfar, where at a spot, now known as McCombie's Field, Broughdearg was slain on 28th January 1673, along with two of Iain Mor's sons. The fine, feud and the crippling law suit that followed ruined the MacThomases, and following Iain Mor's death, his remaining sons were forced to sell their lands.
The MacThomas chief is mentioned in Government proclamations in 1678 and 1681 but the clan was by now drifting apart with some going south into the Tay valley changing their name to Thomson or into Angus and Fife where they became Thomas, Thom or Thoms. The 10th Chief, Angus, who took the surname Thomas and later Thoms, settled in Northern Fife where his family thrived as successful farmers until they moved to Dundee and became prosperous merchants, at the end of the 18th century, finally buying the estate of Aberlemno near Forfar.
(See Migration).
Others moved north into Aberdeenshire, where the name became corrupted to McCombie as well as the anglicised forms Thom and Thomson. In Aberdeenshire, the principal MacThomas family were the McCombie's of Easterskene, and it is one of their party, William McCombie of Tillyfour, M.P. for South Aberdeenshire at the end of the 19th century, who is today regarded as the father of the world famous Aberdeen-Angus breed of cattle.
Patrick Hunter MacThomas Thoms of Aberlemno, 15th Chief, was Provost of Dundee from 1847 to 1853, while his heir, the eccentric George Hunter MacThomas Thoms, advocate, bon vivant and philanthropist, became Sheriff of Caithness, Orkney and Shetland in 1870, donating during his lifetime large sums to St. Giles Cathedral in Edinburgh and, upon his death in 1903, his vast fortune to St. Magnus Cathedral in Kirkwall, together with the Aberlemno estate. Having lost the Aberlemno estate, the chiefly family assumed the name MacThomas.
In 1954, the Clan MacThomas Society was formed and 13 years later, George's great nephew, Patrick Watt MacThomas, was once again officially recognised by the Lyon Court by the historic designation 'The MacThomas of Finegand'.
He died in 1970, being succeeded as 19th Chief, by his only son, Andrew MacThomas of Finegand. It was during his lifetime that the Clan's ancient gathering ground (The Cockstane) was purchased, the new bridge over Shee Water named after the family and the Clan's historic links with Glenshee firmly re-established. Thomas, his only son, was born in the late 1980's.
