Your husband's father is your father-in-law. If that's what you are asking, the wording is a bit confusing.
----
In normal Anglo-Saxon usage, there is no special relationship between spouses' parents or families; each spouse becomes a de facto member of the other spouse's family, but the relationship doesn't extend beyond the spouses themselves. For instance, if your spouse and his parents were to die (god forbid) you would have the right to inherit as a member of the family, but your siblings and parents would have no such rights. This may not hold across cultures - it is conceivable that other cultures would have more defined relationships between spousal families - but it is the case for Western/European descended cultures.well if her husband is considered your son in law, then his father would be considered your brother-in-law.
Your cousin would either be your father's sibling's child, or your mother's sibling's child. That would make them his niece/nephew.
Your wife's father is your father-in-law. Other than in that title only, there is no true family or biological relationship between the two men.
