Original marriage licences, bonds and allegations are available to order. There is also an index to surnames.
A search on Seax for marriage licences and a date will locate the item so that it can be ordered.
Wills before 1858 were proved in ecclesiastical courts. Essex was originally in the diocese of London and records of the courts in the county are deposited in the Essex Record Office.
You can find wills on Seax by searching for a surname or place name and the word will.
There is a three-volume index Wills at Chelmsford ed. F.G. Emmison which lists the wills in surname order. Copies of pages from this can be provided on request for a surname.
The references in the volumes are abbreviated and need to be converted before locating the will. Place D/A in front of the two letters and move the first number to the end, e.g.
21 EW 13 becomes D/AEW 13/21
58 CR 6 becomes D/ACR 6/58
Some wills are from the Peculiar Courts of the Deanery of Bocking (A or D/APb), Good Easter (GE or D/APg), the Sokens (D/APs) and Writtle and Roxwell (D/APw) and their references need further conversion, e.g. 49 AW 2 becomes D/APbW 2/49.
Wills with the letter R in the reference are available on microfiche at Chelmsford, with copies at Saffron Walden, and at Colchester and Southend branches. With these references the second number is the folio number which can be seen at the top right of alternate pages, e.g. D/ACR 6/58 is folio 58 of the volume D/ACR 6.
