Honestly, a family history of inbreeding doesn’t mean much for the individual so long as it’s not directly involved in their own birth. The issue with inbreeding is that every family has a few rare recessive conditions that simply don’t manifest because they’re rare enough to never be shared with the other families that they’re having kids with, but if 2 people from the same family have a kid, that kid is way more likely to end up with 2 broken copies of the gene and have the familial condition.
However, even if your own parent has both broken copies, they can only pass 1 to you, and if your other parent is from another family, they likely won’t have the same condition, so they’ll pass you a working copy guaranteed and you’re good. It’s certainly not ideal, because it does concentrate the broken genes over time in a family if inbreeding continues, but a family history of inbreeding isn’t really much of a red flag health-wise if your own parents aren’t related.
