“Jacob Wiebe … 15.05.1813 … [died] 04.1872 … [father] Jacob Wiebe, Schlablau … Geb. in Simonsdorf” (Ladekopp Familienbuch KB LA 0.3, Prangenau/Altenau section). Wife Anna geb.

Aron’s father (Reid tree). The furthest-back Wiebe in the male line so far. All Mennonite Wiebes descend from one founding Wiebe (Y-DNA) — see Where the Wiebes came from.

The study supports common paternal ancestry among its tested lines, not a documented founder for Jacob. His parents remain unidentified. See Wiebe before Prussia - names and faith networks; no parent link or evidence level has been changed.

Named in their son's obituary

Aron J. Wiebe’s 1922 obituary (Christlicher Bundes-Bote) names his parents as “Jakob und Anna Wiebe, geb.
