Paleogenealogy is the study of ancient family and tribal connections despite a lack of available birth records or during a time before the existence of modern writing systems.
Some of the many available resources used to trace connections are petroglyph clan markers and migration diagrams, language origins, lexicostatistics, architecture, art styles, customs, oral histories, ancient heirlooms, folklore, semiotics, intuition, dreams, shamanic visions, mnemograph markers, cladistics, computational phylogenetics and genetic sequencing.
