What do you say when you introduce yourself and someone responds "that's my [someone]'s name" ?

I have a first name to which when I introduce myself, I often get a response of something like "that's my favorite aunt's name" or "that's my daughter's middle name". It is said as a nice comment and I appreciate the connection, but for some reason I blank and am unsure of how to respond. My reflex is to say "aw, thank you" as if they complimented my name, but that's not quite right lol. What would you say or what would you expect someone to say in response to this comment?
