Thank you so much to everyone who commented (and e-mailed) me about their model stable names! I really enjoyed hearing about all of them.
I've been giving more thought to what mine should be and I'm leaning heavily toward: "Blue Bennu Stables". I've always had a fascination with the legend of the phoenix. My (currently dormant) model/fantasy horse racing stable is called Firebird Farms and I thought about going with that for my model horse stable as well, but I wanted something a bit different.
The Bennu bird is the Egyptian version of a phoenix and may have even inspired the Greek phoenix, which is arguably the most well known. In my research, I found it interesting that many cultures across the world have some sort of phoenix legend. There is even a Japanese version, which I have seriously thought about using as inspiration, given my current location. ;) However, I think I like the Bennu the best. One reason is that it is most often depicted as a heron. The heron is a favorite bird of mine - since that is the last name (slightly different spelling) of my Granddad, Granny, uncles, aunt, etc. "Horse Tender" come from a book of my Granddad's that I had read many years ago. It seems fitting to me that my model stable name in some way be a nod to my Granddad too.
From what I've read, the bird who most likely inspired the Bennu was the grey heron, but I like "Blue Bennu" to be more like the blue heron and, well, blue is my favorite color.
Oh, one other thing, this name - or any variation of it - seems to be available. In other words, I can't find another Blue Bennu Stables mentioned anywhere. That's a plus.
Yes, I think I've just about talked myself into it...
