I’m not sure what you mean by ‘matriarchal duties’ are but unless they’re for young children that she’d be leaving behind, that’s not a tie. Neither are revenue sources. Only the family business is a tie but what do you mean by ‘overseeing’? Is she actually running the business day to day?
If she was only refused last month then reapplying again isn’t going to help. Unless anything’s changed with her circumstances then it’ll be refused again and she’ll look even more desperate. When was the first application? I’d leave it at least a year, and as @TBoneTX said, get her to visit other countries before applying again. In the meantime, you visit her.
Good luck.
