Marrying within the extended family—even several generations apart—slightly increases the statistical probability that both partners share common recessive genes inherited from their shared ancestors.
Next Steps
Preconception Genetic Counseling: A formal session with a genetic counselor can map out a detailed pedigree chart to evaluate the exact coefficient of inbreeding.

Marrying within the same extended family, even a few generations apart, does raise the chance that both partners carry the same recessive gene, which can surface as a genetic condition in a child only if both parents happen to carry it.
Next Steps
The actual risk depends on how closely related you are and whether any conditions run in either family, so a preconception genetic counselling session with blood tests can give you a real picture instead of a guess.
Health Tips
This isn't a reason to assume a problem will happen, most children of related couples are healthy, but please consult your doctor or a genetic counsellor beforehand.
