The other researcher (family tree that said Glack) had no sources what so ever. They just had a map picture with the name Glack on it but it did not show the county. (I have attached the picture I copied) She has it labeled "Glack in Kirkmichael". It's hard to read but there is a name to the right that says Nethertown, a name under the word Glack says Pootwick or Footwick and a name above Glack that says Allanreid. Other names on the map are Glenlivel, Tullich, and Whitefolds.
I couldn't pull up a Nethertown.
Allanread comes up as a ruined farmsteading situated near the banks of the River Livet (Canmore). Glenlivel comes up as the Battle of Glenlivet 1594 near Allanreid and Morinsh.
Glenlivet is the glen in the Scottish Highlands through which the River Livet flows (doesn't list a county).
Whitefolds comes up as Whitefolds Farm, a prospering Scottish red meat industry and Whitefold Wood, Perth and Kinross. The Gazetteer for Scotland - Moray, lists a Whitefold.
Pootwick or footwick pulled up nothing.
Tullich is a village in Aberdeenshire, Scotland (The Battle of Tullich, in 1652).
The family I have been researching is Fraser.
Father: William Fraser b. 1767 Scotland d. pos Banffshire, Scotland
Mother: Marjery McKenzie b. 1768 Scotland d. pos Banffshire, Scotland
Children:
Isobel Fraser b. 1786 Glack, Kirkmichael, Banffshire, Scotland
John Fraser b. 1789 Glack, Kirkmichael, Banffshire, Scotland
Helen Fraser b. 1792 Glack, Kirkmichael, Banffshire, Scotland
Margaret Fraser b. 1794 Glack, Kirkmichael, Banffshire, Scotland
James Fraser b. 1801 Glack, Kirkmichael, Banffshire, Scotland
They all died in Keith, Banffshire, Scotland.
I have found birth registrations for 4 of the 5 children. They list the place of birth as Kirkmichael, Banffshire, Scotland. No mention of Glack so again I have no idea where this other person got the name Glack from.
I know that I have found other family member's death certs that have listed the name of the farm they lived on but they also list the city or county so I am thinking, like suggested, that Glack is just a reference to a location within Kirkmichael (ie. Farm or Croft) and not a town.
