A bit more on the Willingham-registered children (I think!)
Hezekhiah Cross Willingham married Dec 1870 Ely to either Hannah Rice or Eleanor Ann Hopkins, haven't found them in 1871 to establish which; Alexander has been mentioned before; Rosetta married in 1877 to either Henry Bye or William Crabb; Cinderella had a child, John William S Willingham in Jun 1883 Ely, married James Rice in 1886 and by 1901 had children: Elizabeth 1886, Frances 1889, Arthur 1893, Rosa 1895, Florrie 1898 and Ernest James 1900. In 1891 Cinderella's grandmother Frances was with them. Looks like Benjamin Cross died in 1877, Frances remarried in 1879, to William Custance. He died in Sep 1881 Cambridge. Frances died Mar 1895 Ely.
Haven't found Susan Cross. Ann seems to have had brothers Isaac b 1830 and Abraham b 1832, so scope there. Also found three sisters called Caroline: No 1 born 1836, died 1838; No 2 born 1839 died 1840; and No 3 born 1840.
