wedding website question

I'm working on my wedding website and have a page for my bridal party.

I am noting the relation to each person.

So, my brother's girlfriend. Do I put her down as 'friend of the bride' or something like 'future sister in law' or ???

FH's sister -in-law...do I put her down as 'Groom's sister in law'...or just 'sister in law'

i would put brother's girlfriend as either friend of the bride or friend of the bride's family

groom's sister-in-law i think should be worded as such

HTH!
