Robert Gruenke (1914 - 1996)

The proposed relationship of Robert Gruenke as the father of EBG and DG is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a great aunt / uncle relationship between JG (a descendant of the DG ancestral line) and AB (a descendant of the EBG ancestral line) with a shared segment of 1005.06 cM across 34 HIR segments.

This match is consistent with their placement within these shared ancestral branches.
