EXPLANATIONS. 1. WHEN places other than Sudbury and Massachusetts are named in the original records, they are given in the printed copy. 2. In all records the original spelling is followed. 3. The various spellings of a name should be examined, as items about the same family or individual might be found under different spellings. 4. Marriages are printed under the names of both parties, but the full information concerning each party is given only in the entry under his or her name. Prior to 1850, there are no records of intentions of marriage, and but few records of deaths, found in Sudbury. 5. Additional information which does not appear in the original text of an item, i.e., any explanation, query, inference, or difference shown in other entries of the record, is bracketed. Parentheses are used only when they occur in the original text, or to separate clauses found there - such as the birth-place of parents, in late marriage records. 6. The double date is used in the months from January to March inclusive, prior to 1752, only when it so appears in an entry.
