Source-derived summary

William Plocker (May 28, 1811 – December 20, 1878) was an English-born Dutch-American immigrant, farmer, politician, and Wisconsin pioneer. He served in the Wisconsin State Assembly, representing Fond du Lac County.

Biography

William Plocker was born in London, England, but raised and educated in Amsterdam, Netherlands. He emigrated at age 16, landing in Boston, Massachusetts, on July 1, 1827.

Two years after arriving in Boston, he moved to Orleans County, New York, where he worked as a farmhand, taught school courses, and clerked for local businesses. He prospered in New York, and was appointed collector of canal tolls at Brockport, New York, in 1839 and 1840, and was named cashier at Buffalo and Albany, New York, for the Western Transportation Company. From 1845 to 1847, he worked aboard the steam ship Wiskonsan, first as clerk and later as master, making a circuit between Buffalo and Chicago. Because of these years of nautical work, he was often referred to as "Captain".

In 1847, he chose to settle in the Wisconsin Territory, and purchased land in the town of Metomen, Wisconsin, near the village of Fairwater, in Fond du Lac County. Within a year of his arrival, he was appointed postmaster at Fairwater.

Editorial analysis

Why this record matters

“William Plocker” is worth following because a concise public description often conceals a longer documentary argument. Here, William, Plocker and American provides the most credible route into that argument.

Evidence profile

Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Jul 24, 2026. The linked authority identifier is Q19519168. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1811, 1878, 1827 and 1839.

Critical limits

Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
