T. J. vs. T. K.

I've made it back to the UK, but my internal clock is still off. This morning I used some of my time while I couldn't fall back asleep to solve the dilemma of what came first: T. J. Maxx of the US or T. K. Maxx of the UK.

It is all documented in this wiki article: http://en.wikipedia.org/wiki/TJX_Companies

To summarize, TJX companies was founded in America and used the T.J. Maxx name for their stores. After spreading across the US, they made another in the UK and changed the name for here to T.K. Maxx.

To summarize the summation, the US store came first, then the UK store. Who is copying whom?
