Perhaps Donald Campbell DNB 1751-1804 whose will PCC 1804 dated 5.5.1804 mentioned his reputed son William aged 2 or 3 years and Augusta Kendall, probably the mother. His legitimate son Frederick William is also in DNB 1782-1846 so could have been included in the plural Campbells as well as his mother Mary whose dates are not given in DNB
