In one of my sources, the tartan associated with the surname Crofton is the Clodagh tartan, an Irish district tartan. Another possibility would be to identify the area in Ireland and Scotland where your ancestors live, and wear the tartan of that district/tartan. A third possibility would be if you know which regiment an ancestor served in, to wear the tartan associated with that regiment in honour of your relative.

Calderwood is associated with the Strathcylde district in one of my sources, so that district tartan would be appropriate, and if the name is associated with the Maxwells, a border family, you could always wear it, although keep in mind that the Maxwells who were border reivers would have not worn a kilt historically, although many Lowland & Border families have now adopted tartans & kilts to show their Scottish heritage. A good friend of mine is a Maxwell, and the tartan is quite nice!

Hope this helps! :mrgreen:
