Using family names

Does anyone else feel guilty for not using family names? Pregnant with our second baby and trying to decide on names. For our son we used a family name for both the first and middle name. My name is also a family name. I don’t know why I get so caught up on choosing a name that is not a family name. Can someone help me think of choosing a name I love that is not a family name in a more positive way? I think we would love to do a first name that we love and then a family name for the middle but I feel so weird about just choosing a name at random that we have no connection to - I know this is crazy and doesn’t make sense.
