I don't think there is any problem with having a hyphenated last name. When DH and I got married I didn't want to give up my last name either so I now have a double surname (no hyphen) it is my maiden name and then my DH's surname, kind of like Jennifer Love Hewitt iykwim? It can be a PIA cos a lot of companies databases don't like double surnames without a hyphen, so when DS was born we decided that he would just have DH's surname. We recognised my family history by giving him my fathers middle name (which was my grandfathers first name) and if when we have another child will do the same thing - first name is something we choose together, middle name comes from my family and surname from his.
