There is a marriage that leads to children: 5 Apr 1825 • St Martin's Church, Birmingham, Warwickshire, England Family Search: Thomas Millington; Marriage 5 Apr 1825 Place: St Martin, Birmingham, Warwickshire, England; Spouse Elizabeth Summerfield; GSF 919783,919782 Digital Folder Number 77760361 Indexing Project (Batch) Number M01072-3 System Origin ODM Children were Thomas b. 1827, Sarah b. 1831, Caroline b. 1837, Mary Ann 1 b. 1838, Mary Ann 2 b. 1840, Emma b. 1843, Elizabeth/Betsy b. 1846; these all turn up in appropriate Censuses. There is also a mother-in-law Elizabeth/Betsy Millington in two. All the BMD-registered births say MMN is Bird. As there is a sizeable gap between Caroline and Mary Ann 1, maybe there was a death and re-marriage but I cannot find one. Any clues from folks who subscribe to sites other than the big A?
