While visiting my family over the holidays the topic of taking your husbands name came up (I hopefully have 2 cousins on their way to the engagement road).
They had asked what I thought and what I did with my middle name. It was a not an issue for me to take my husbands name, I never thought twice. Although Tomasulo is a lot harder then Sellers! I just wanted to change my name - made it feel more like creating a family. I am more on the traditional side but I did make my maiden name my middle name though.
I know some people are concerned about their professional lives and if they have been 'Karen Somers' forever it would be weird to drop the 'Somers.' Well you don't have to drop it completely.
I was Meredith Sellers for over 30 years so dropping Sellers didn't seem right either so I dropped Ann and became Meredith Sellers Tomasulo. I think years ago this was the more Southern thing to do (surprise surprise). Ann wasn't as important to me as Sellers was/is.
Professionally in the wedding business people knew me as Meredith Sellers so I just added Tomasulo to the end then after about a year I stopped including Sellers in my correspondence and business cards. Easy transition.
This is entirely a personal choice and I know some people really fret over it. Just do what is right for you and your new family.
What do you plan to do?
