Hello Kylie,
To search the Quaker registers from the Main page on thegenealogist :
Click on "Research View" in the top left corner.
Then click on "Search" Non Conformist and Non Parochial Records.
Then click on More Options : "Advanced Search".
Then in Surname enter Unthank, or shorten to Unt if you want to see all names beginning with those 3 letters (useful if searching for a name like Pursglove which can be misspelled many ways).
On Search Within, select "RG6 : Quaker Registers 1578-1841".
On Search Place type in "Yorkshire" or leave blank if you want to see them all.
Then "Enter".
You will see 5 pages of Unthank/Unthanke Quaker records in Yorkshire, about 120 records, including in the Guisborough records the birth of Rachel Unthanke 1712, daughter of George and Mary. A lot of the records are not indexed, presumably because they are hard to read, so it pays to just flick through registers page by page if you are looking for something in particular. There is a marriage of George Unthank of Danby and Mary Shipton of Whitby 2nd Feb 1703, on page 216 of the Guisborough register, RG6 1092, but its not in the index.
I still can't see a Robert Pursglove marriage to a Rachel in the Quaker records though.
The Robert Pursglove and Rachel Unthank marriage took place at Scarborough Anglican Church (Church of England), 16 Feb 1739, according to the FamilySearch England and Wales Marriages database (from Bishops Transcripts). These are extracted records so are pretty reliable. The IGI extracted records don't cover that date, the marriage record on the IGI is a "Member submitted" entry.
Happy hunting.
Alan.
