Surname Origins & Immigrant Streams

Tracking the ethnic origins and Americanization patterns of family surnames. Useful for understanding the cultural landscape that produced the family, and for searching records under original spellings.

Walloon Belgian (Brabant → Wisconsin Belgian Corridor)

Settlement area: Dyckesville, Robinsonville (Champion), Red River, Union — Brown/Kewaunee/Door Counties, Wisconsin.

Key villages: Mélin and Beauvechain in the commune of Jodoigne, Walloon Brabant. Both the Coppesmette and Lancelle families came from these neighboring villages. They married in Robinsonville (now Champion), Wisconsin — the Belgian Catholic settlement.

French-Canadian (Quebec → Wisconsin)

Settlement area: Fond du Lac County, Outagamie County (Maple Creek, Deer Creek), Waupaca County (New London) — central/eastern Wisconsin.

Deep Ancestry (pre-Quebec, France → New France immigrants)

Other French-Canadian Surnames in the Tree

Key origins: St Athanase sur Richelieu, Iberville, La Prairie, Chambly, and L’Acadie — all within a 20-mile corridor along the Richelieu River south of Montreal (now part of Saint-Jean-sur-Richelieu and surrounding municipalities). The Young, Surprise, Bodoh, Balthazar, Lavallee, and Guyette families all came from this area and likely knew each other before emigrating.

The “Dit” naming convention is a hallmark of French-Canadian genealogy — families carried two surnames, the legal name and the “dit” (called) name, and different descendants might Americanize one or the other.

Two Streams Merging

Dorothy Elaine Coppersmith (1928–2002) represents the convergence:

• Father Claude — Walloon Belgian (Coppesmette/Coppersmith from Mélin, Brabant)
• Mother Marie — French-Canadian on both sides (Beaudin Dit Bodoh + Young/Surprise from Quebec)

Both streams arrived in Wisconsin in the mid-1800s, settled in adjacent counties, and merged when Claude married Marie in Green Bay in 1926.

Depth of the Two Streams

• Belgian side: Traced to 1700s in Brabant Wallon (Mélin, Beauvechain). ~5 generations documented.
• French-Canadian side: Traced to 1588 France (Pierre Desportes, Lisieux). Through Helene Desportes (b. 1620 Quebec), connected to Louis Hébert — the first European farmer in New France. ~10-12 generations documented. Six immigrant ancestors identified: Jacque Beaudoin (La Rochelle), Francoice Durand (Rouen), Jacques LeBlanc (France), Jacques Surprenant (France), Pierre Goguet (Picardy), Noel Morin (Brittany).

German (various regions → Wisconsin & Minnesota)

The largest single ethnic thread. Ancestors came from across the German-speaking world — Baltic coast to Black Forest.

Settlement areas: Door County (Pfister, Mielke), Le Sueur County, Minnesota (Schmidt, Vollmer, Kurtz, Schindler), Kenosha (Schneider).

Bohemian/Czech (Chodsko region, western Bohemia → Wisconsin)

All three families from the Chodsko region — the Domazlice/Klatovy area of western Bohemia near the Bavarian border. Trhanov and Domazlice are 5 km apart. The families were intermarried before emigrating. Parish records digitized at portafontium.cz.

Settlement areas: Oconto County, Shawano County (Leopolis) — Wisconsin.

English (Kent → Minnesota; Northumberland → Canada → Wisconsin)

The Kent cluster (Kendall, Forstall, Lambert) all came from Wingham and its surrounding parishes — a single community that reassembled in Minnesota.

Irish — Ulster Protestant (County Down → Wisconsin)

Evidence for Protestant/Plantation origin: English surname “Storm” (mother), Protestant funeral (Rev. David Lewis), Christian Science in next generation, biblical name “Eliphalet” for youngest son. No Catholic markers anywhere in the line.

Scottish (Perthshire → Newcastle → Canada → Wisconsin)

Migration path: Rhynd, Perthshire → Newcastle upon Tyne, England → Canada → Door County, Wisconsin. Four countries in four generations.

Schneider — Additional Notes

The mother Mathilda/Mathilida Schneider (b. c. 1873, Germany) — maiden name unknown. Immigrated 1892. Both parents German-born. Died 1912, buried Kenosha. The only remaining unknown maiden name that could theoretically add a new country, but 1900 census confirms both her parents were German. No surprise expected.
