I didn't change my name for the first marriage, which turned out to be a good thing.

I was a bit hesitant to change my name for the second (current) marriage because I have publications, etc. in my name. However, there were three reasons I decided to do so:
- he preferred it
- we are planning a family
- my first initial/last name makes an unfortunate combination when used for work login accounts, would be nice to not have that anymore

I'm starting the process now, we were married 4 months ago but we were also in the process of buying a house, wasn't a good time to mess around with paperwork and legal records.

I'm keeping my original middle name, but for work purposes I will probably include my "birth name" (like that term) on business cards, etc.
