Baby Name Poll

Ok, so this isn’t exactly a poll for names but I figured it was a great place to get opinions on the subject. Is it alright to "take" a name that one of your sisters likes? Even if she is not married and not planning on having kids for a while. So who knows if her future husband will even like the name, right? Dh likes a name and suggested it to me, I didn’t like it at first just because I knew my sister did but now it has really grown on me. Just some fyi for you too...I have seven sisters (three bio and four step) and some of the names I like and planned to maybe use were taken by some of them. Thank you all for your help and opinions on this subject.
