My last name is actually my dad’s first name…and not his family name.
Ria, just keep your maiden name. If your SO has no issues about it, then that makes it even easier. It’s unreasonable (IMO) for anyone else to have problems with it.
One of my desi friends kept her maiden name…her husband had no issues with it. The husband’s dad, however, was hinting to the both of them that she “should” change her last name. But…he supported his wife…it remained as is. They’re MashaAllah happily married with 2 kids.
