What Is a Great-Great-Grandson?
A great-great-grandson is the male descendant who is four generations below a common ancestor. He is the son of a great-grandson, meaning his lineage goes grandchild, great-grandchild, and then great-great-grandchild. In standard kinship terms, this is the fourth generation after the grandparent.
Inheritance and Legal Relevance
In estate law, a great-great-grandson may inherit as a direct descendant if no closer relatives survive. Intestacy rules in many jurisdictions prioritize children, grandchildren, and great-grandchildren before more distant descendants. For specific statutory guidance, you can refer to the legal overview at Cornell Law Institute.
Tracing Great-Great-Grandson Lineages
Genealogists trace a great-great-grandson by documenting birth, marriage, and death records across four generations. Standard records include census data, civil registrations, and parish registers. DNA testing can confirm biological relationships when paper trails are incomplete.
