The paternal relationship between Abraham D Thiessen and his daughter ALT is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant LRY.
The segmental (via DNA segment triangulation) and total DNA shared between LRY and other confirmed descendants of
Dietrich Thiessen/
Elisabeth Huebert is consistent with the expected ranges for their respective relationships. Since LRY descends from Dietrich Thiessen/Elisabeth Huebert through Abraham D Thiessen and his daughter ALT, the presence of significant shared DNA between LRY and other known descendants of Dietrich Thiessen/Elisabeth Huebert validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple Dietrich Thiessen/Elisabeth Huebert through Abraham D Thiessen to ALT, and ultimately to LRY, confirming this direct ancestral connection through multiple generations.
