Bayside and Newburg are split-county villages: most of Bayside’s population lives across the line in Milwaukee County, and most of Newburg’s lives across the line in Washington County, so only a small share of each village is technically in Ozaukee. “Kohler”, which appeared on older lists for this county, is actually the separate village of Kohler in Sheboygan County and has been dropped here; the genuine Ozaukee community of that name is the unincorporated hamlet of Little Kohler, listed above.<\/p>\n
