I don't think it's a good idea to do business with your relatives unless you trust them implicitly in anything and everything. Or else it could lead to a messy situation and you wouldn't be able to do what you want with your business.
Recently we hired people( distant relatives) for the maintenance of our property. Now, we are not able to question them, when they are slacking off. They keep saying that, they are working really hard even when it's clear that.... it's not the case.
We really thought supporting and hiring people we know, would make our job easier but we regret it now. So, doing a business with your relatives or hiring your relatives, is not at all a good idea, unless you know them very well. Do you guys feel the same as well?
