I can't speak for Derbyshire but I am researching Broadleys in the West Riding of Yorkshire. We got back to Yorkshire from Lancashire via a Y-DNA project. I am searching before 1632 when Abraham Broadley was born. I am slowly buying all the Broadley wills. I would also say, if you can, look at all the other wills in the same area. I have found many Broadleys as witnesses, which hints at marriages before parish registers. If you can put people into a larger group, whether marital or socio-economic, it helps to trace members of that group. Taxation is useful. The Poll Tax was 1379 and then there are various Lay Subsidies which will tell you how rich your ancestor was. I don't know what the survival for Derbyshire is. I have searched TNA and local record offices for documents online under many spellings. If someone is having property handed over to him, this may again be a clue to a marriage. I have Googled all sorts of related words, places, etc. I have read background books on the history of the area. I have looked at trees of people who married in. There are also Manorial Records- what is the coverage of those in Derbyshire? Are there any religious charters? Although I can go forward from 1362 when John Broadley (the first Broadley) built Broadley Hall and I can go back with certainty to about 1480 to unknown Broadley father of Richard and William, it is clear there are more people existing than appear in the records I have found. I am certain of the 1300s and the 1500s but the 1400s are still unclear. I do apologise if you know all this already. Anyone who would like to offer me advice on mediaeval research is very welcome! Have you read George Redmonds' Christian names in Local and Family History? Before Cromwell, people called their children after godparents, who might be family members but also, often, their landlords. If you are lucky enough to find an unusual first name, it may help to make deductions.
