In genealogy terms what do you call a relative by marriage?

Answer 1

A relative is someone who shares a common ancestor with you. A relative by marriage is someone who does not share an ancestor with you but has married someone who does. In the most common instances of this relationship, the words "in Law" are added to the description of the relative. For example, a Brother in law is someone who is married to your sister, or is the brother of your wife.

The word being looked for is "Affine"

Kinsman or Kinswoman

Answer 2

A relative by marriage is an in-law. There are a limited number of such relationships in the English language. They are: * father-in-law (father of your spouse) * mother-in-law (mother of your spouse) * sister-in-law (sister of your spouse or wife of your brother) * brother-in-law (brother of your spouse or husband of your sister) * son-in-law (husband of your daughter) * daughter-in-law (wife of your son) Although some try to apple the "in-law" concept more broadly, these are the only ones generally accepted in the English language.
