If MS appears only for females, it means Maiden Surname, that is, the mother's maiden name.
- in 1855 the death Registration form had a column for Parents Name, Rank, Profession or Occupation. The mother's married name was given on one line. On the next line was Maiden Name followed by the mother's original surname.
- after 1860 the parents column was headed Name, Rank Profession or Occupation of Father and Name and Maiden Surname of Mother. The registar entered the mother's married name on one line and then MS Surname on the next.
e.g. the entry for a child of John Smith and Mary Brown would be in the form:
- John Smith,
Occupation
- Mary Smith,
MS Brown
