opinion on name issue please

okay so heres the story. Before my husband and I even found out what sex the baby was we like the name Corbin. It was our first pick from day one. I was telling my mother the name we were thinking. She mentions that she thought was the name brother an sister n law had picked out if they had a boy ( but they had a girl in September. They never went public with their names. After my mother told me that I felt obligated to ask them. They told me they still really liked the name. Then my mother informed me that she wouldn't of said anything to them since they didn't tell everyone. My husband and I have tried to come up with another name but Corbin is still our number one pick. My husband still really wants to use that name but I really don't know what to do on the situation. Talk to my brother and explain to him that corbin has been our top choice since before we found we were having a boy? also who's to say they will ever have a boy or decide on a different name when they do?
