In the English language there is no difference between the wife of an elder brother and the wife of a younger brother or of a twin brother. The wife of any brother is your sister-in-law. If you are actually talking to her, however you should just call her by her name. Nicknames are fine too.
just call her by her first name, she is no relation to you.
