Fòram na Gàidhlig

So I have a new Amazon Kindle, and I'd like to see a Gaidhlig name on it, but I'm having a little trouble.

I'd like it to say in a nut shell "Mairghread's Kindle"

The only help I could find was Lesson 14 on "Taic", and I could simply copy what it says and use "a leabhar fhèin" or "mo leabhar fhèin"

But I'd like to take it a step further and instead of just "Hers" or "Mine" have "Mairghread's" Would I add it on to those and leave either an "A" or "Mo," or would I omit them?

Also, would you leave the "Leabhar" or could I use a more literal tr*nsl*t**n with " beothaich" or "fadaidh" (I know, verbs, but still! lol)

Thanks in advance!
A beginner
(ps, I know I know, but I did most of the T********** work on my own!)

I would put that as An Kindle aig Maighread

Alright thanks!!!

I'll use that then!
