What would you consider incest? Do the bride and grooms families get related through marriage?

*Cheerios: What would you consider incest? Do the bride and grooms families get related through marriage?
As in, would a sister of the bride be related to a brother of the groom? How about cousins of the groom? Would they then become cousins of the brides family? It would be related through marriage I guess, but does that really count as being related therefore no family member of the bride could ever marry a family member of the groom? Would it kind of be like incest? haha

No incest – unless your blood related even if the bride and groom don’t get married.
