There were four early Quaker meetings within the bounds of present-day Delaware County, plus one in Chester County. In the early years all this area was part of Chester County. ¹ The records of Radnor Monthly Meeting are included in Delaware County, along with Concord and Darby. The records of Chester Monthly Meeting are split on Ancestry, between Chester County and Delaware County.

The earliest vital records of the meetings are found on Ancestry, just like the vital records of the early meetings in Bucks and Philadelphia Counties. If you have a subscription you can view the images there.

There are four sources of vital records for Chester Monthly Meeting, one each for births, burials and marriages, plus an early record book with a mix of births, burials, subscriptions for collections, and other material. With its original handwriting it is an evocative glimpse into the life of the meeting. The records of births and burials are later copies, probably around 1884, since the records stop there.

Meeting	Vital record	Ancestry file
Chester	Births	"Births 1677" (later copy, index in back)
Chester	Burials	"Burials 1682" (later copy, no index)
Chester	Marriages	"Certificates of marriage, record" (full certificates with witnesses, no index)
Chester (under Delaware County)	Births, burials, marriages	"Register Book 1681" (a mix of records, original handwriting)

The vital records of Concord are incomplete for the early years. The records of births and marriages start around 1693, with a few earlier births in another place, and there are no apparently no early deaths.

Meeting	Vital record	Ancestry file
Concord	Marriages, starting about 1693	"Births and marriages 1693-1808" (certificates with witnesses)
Concord	Births, early	"Minutes 1680-1701" (actually births, early handwritten); also "Minutes 1685-1931" (late copy, incomplete record)

Darby Monthly Meeting handled its early marriage certificates in a distinctive way. Instead of being copied into a register of their own, they are written in with the minutes in the proper chronological sequence. Once in a while the recorder left a blank space for the certificate, but it was never brought in to be copied. The record of births and burials starts early.

Newark/Kennett meeting was originally called New Ark, later changed to Kennett. Don’t confuse it with the meeting in nearby Newark, Delaware. Ancestry lists its records for Kennett under Chester County, as they should be.
