The Origin Of "Mordearthair"

I was simply looking for a title to the new photo album. I wanted it to be somehow related to Aidan becoming a big brother but "Big Brother" seemed too...ordinary. So I found an English-Gaelic dictionary online and found the words for "big" and "brother," removed all the accent marks, and smushed them together. The result is "Mordearthair." A very legendary-sounding name, isn't it? I googled it and the only thing that came up was my own blog. Maybe I'll use it as a character's name someday. Until then, it's definitely a nickname for my Little Fire.
