G'd afternoon all!

Another question from a newbie forum member here, unsure if it's been covered before but just asking for some opinions.

A little backstory first. My mother had a best friend, essentially a sister with whom my entire family was very close with. She was born a MacKintosh, a family with no direct link to my own. In addition to my ma's best friend for 20 years, this woman functioned as a surrogate mom for my siblings and I on several crucial occasions (for example, my younger brother required an emergency trip to the hospital and an appendectomy. My mother called Kim [which was this fine woman's name] at 3:00AM, to which Kim responded "I just unlocked the front door, get Cass here as quick as you can so you can get Nick to the hospital." Didn't think about it or hesitate, but her friends needed help and come hell or high water, she was going to help us.)

Unfortunately, Kim slipped the bonds of earth due to a very rare and aggressive form of brain cancer about 8 years ago to which she herself had lost a child.

I'm currently searching for my next tartan to purchase a kilt in and was thinking a Mackintosh. I guess that my whole question is: if you were a member of a clan and saw someone wearing your tartan, would someone explaining that they were doing it out of respect and to honor an individual that carried that name, would you be likely to take offense or think it at all out of turn for someone to wear your tartan?

TIA as usual!
