This is not every date in the research file. It is the clean storyline version: the moments that best explain how the family trail fits together.
1691
Earliest Lohr-side tree clue points to Heinrich Löhr in the Stommeln / Nettesheim region. This older part is still tree-backed and needs more church-book image checks.
1766
A compiled tree claims Peter Löhr was born in Stommeln this year, but the checked St. Martinus church-book window (BA 2450 S067) shows no obvious entry - an honest unresolved clue.
1794
Johannes Bryngelsson born/baptized in Fölene, Sweden (Nov. 24/25); backed by a Riksarkivet church-book image.
1836
Johan Johansson, later John B. Johnson in family records, is born in Eggvena, Sweden. This is backed by Swedish church-book images.
1845
Mathias Löhr is born in Butzheim. His public German civil birth certificate image is one of the strongest records in the whole packet.
1867
Mathias Löhr, age 22, appears on the public Amt Nettesheim emigrant list, leaving Butzheim for North America/Illinois.
1870
Patrick Green and Elizabeth Callaghan appear together in the official New York City marriage index. This is strong for the event, but the Elizabeth/Margaret name question remains open.
1872
Mathias Löhr marries Helena Lellman in Fond du Lac County, Wisconsin (Jun. 25 or Jul. 25 - sources disagree).
1874
Barbara Meurer Löhr dies in the Anstel/Nettesheim area; her civil death certificate image (No. 1874/19) is saved locally.
1893-1898
Public land records place John B. Johnson in Day County and Patrick Green in Clark County, South Dakota. These records support the South Dakota settlement story.
1895
Jacob Löhr dies at Anstel, age 89, widower of Barbara Meurer; certificate No. 38 image saved.
1907
Walter Marcus Lohr is born near Raymond, South Dakota, according to public biographical material.
1916
Nels A. Hanson dies in Troy Township, Day County - the man family sources say donated the St. Ansgar church and cemetery land.
1919
Patrick Green and Mathias Löhr both die; Patrick in the Clark County area.
1932
Anna Mathilda Johnson Hanson dies at Lily - but public trees disagree on Aug. 23 vs Sep. 23.
1935
Walter Lohr marries Frances Elizabeth Hanson, bringing the Lohr/Greene and Hanson/Johnson branches together.
1937
Jerry Lohr is born in Clark, South Dakota. Public biographies later connect him to SDSU, Stanford, and the founding of J. Lohr Vineyards & Wines.
1992
Walter Marcus Lohr dies at Watertown. An Argus-Leader obituary snippet says Jun. 13; Basin Electric says July - Jun. 13 is the better-supported working date.
