My "also known as" is nearly half a page long, LOL!
I've been married more than twice, I'm a little embarrassed to admit, and that has complicated my name issue. I took my husbands' names, had daughters by two of them - different names - and then named myself in my final divorce in 2001 and had it written into the decree. I chose a name from my mother's distant past and a name from my father past and hyphenated them into my last name. I also legally dropped the "et" from my first name.
It has caused me quite a bit of hassle because hyphenated names are uncommon in Virginia (unlike Hispanic-rich Texas, where I living at the name change time). Here no one seems to know whether to call me by one name or the other. And, simple as both names are, they refuse to see how to pronounce the last one. At the doctor's offices, the nurses have mostly given up and just call "Jan" to the exam room, LOL!
