Mil is the old spelling of "thousand" used in written-out years, as in mil huit cent quarante-deux, 1842.
French records often write the date in words, and the year begins with mil, an old form of mille that by custom was preferred when other numbers follow. Mil huit cent soixante means one thousand eight hundred sixty, 1860. Both spellings were accepted for dates.
Read the year in parts: mil, then the hundreds (sept cent, huit cent), then the rest. Watch the compound numbers, since 1790 is mil sept cent quatre-vingt-dix, literally one thousand seven hundred four-twenty-ten.
