Legal Definitions - consanguine brother

A consanguine brother refers to a male sibling who shares the same biological father but has a different biological mother. This term specifically highlights the shared paternal lineage when distinguishing between siblings who may have different mothers.

• Example 1: Inheritance and Family Lineage

  Mr. Henderson had a son, Mark, with his first wife. After his first wife passed away, Mr. Henderson remarried and later had another son, Alex, with his second wife. In legal documents or discussions about family inheritance, Mark and Alex would be referred to as consanguine brothers.

  Explanation: Mark and Alex share Mr. Henderson as their biological father, but they have different biological mothers. This makes them consanguine brothers, a distinction that can be crucial in wills or estate planning, especially if a will specifies beneficiaries based on paternal bloodline or if intestacy laws need to determine heirs among half-siblings.

• Example 2: Genealogical Research

  A historian is researching the family tree of a prominent 19th-century figure, Thomas Miller. Records show that Thomas Miller had a son named Edward with his first wife, and after her death, he had another son named George with his second wife. The historian notes that Edward and George are consanguine brothers.

  Explanation: Edward and George are consanguine brothers because they both descend from the same biological father, Thomas Miller, but were born to different biological mothers. In genealogical research, accurately identifying these specific sibling relationships helps to correctly trace family lines and understand the full scope of a family's paternal connections.
