hi hi! just wanted to pop in to say your guide to regency names is a godsend as an amateur regency historian and hopeful romance writer!! the tier system is perfect, and it's made me feel better about all the characters I slap the name Mary onto. did you ever get around to doing some work on nicknames and/or accurate surnames? I'd love to hear of any primary sources you have for those two topics!
I'm so glad you find it useful! It's honestly kind of my magnum opus as far as getting an idea, researching it, and actually presenting it in a format people seem to understand in a timely matter (that last one is my downfall as I am not good at finishing things).
I worked on the nickname followup for about four months after I did the Regency guide, but was (and still am) at a loss with how to both measure and present my findings.
The problem with nicknames is there is hardly any quantifiable data.
With the first name survey I used two pre-existing databases for my info - so my workload was pretty much just making a spreadsheet, eliminating any duplicate records, and counting how many times each name occurred.
I was also working in only one very specific area (7 parishes in London) so I didn't have to worry about regional variations.
Due to the strict formally of the Regency era, nicknames do no not often appear in legal records, and were usually only used privately among families and very close friends.
When they were used publicly it was often only with members of the 'lower' classes - and I don't mean that in the modern economic sense, but rather referring to people who were seen as 'lesser' in social status - this included children, unmarried women, servants (both free and enslaved) and the poor.
Nicknames do sometimes appear in vital (birth/marriage/death) records, but even then it's often impossible to tell what the nickname is actually short for - e.g. is Patty short for Martha or Patience? is this person listed as Eliza because it was their given name or was it short for Elizabeth?
Nicknames also vary heavily by region - to the point that some are specific to only a handful of counties. I considered focusing on only nicknames used in London, but honestly the regional variation is one of the most interesting features of nicknames to me.
All these facts mean that my research process was exceedingly more complicated than with the first name survey.
With a lack of quantifiable data I approached the project with three basic questions:
Was this nickname in use during the Regency era?
I then had to determine this individually for every single possible nickname used with common Regency names. Do you know how many possible nicknames there are for Catherine? For Elizabeth? (Many. There are so, so many you guys.)
On top of having to research each nickname individually, I also didn't have a single source of information like in my previous project, and ended up using everything from period literature to newspapers to court testimony.
As I keep finding new sources, my info keeps changing and so far all my attempts to do a decent write-up have failed. But here's a bit of what I've found so far...
Nicknames for Common Regency Names
Mary - Polly, Mally (northern England/Scotland), Molly (Lancashire), Pally (Yorkshire)
Elizabeth - Eliza, Bets(e)y, Betty, Lizzy, Bess - NOT Beth
Ann - Nancy, Nanny (northern England), Annie (Scotland)
Jane - Jenny, Jessy/Jessie (Scotland)
Hannah - ??? but likely the same as Ann
Susannah - Susan, Sukey, Susy, Suckey (southern US)
Margaret - Peggy, (Maggy, Meggy, Moggy, Madge (Scotland))
Catherine - Kitty, Kate, Cat(e)y (US), Catty (Ireland), Katie (Scotland)
Martha - Patty, Matty (northern England/Scotland/Ireland/US), Patsy (southern US)
John - Jack(y), Johnny, Jock(ey) (Scotland)
William - Bill(y), Will(y)
James - Jem(my), Jamie (Scotland) - NOT Jim
George - Georgey, Geordie (Northern England/Scotland)
Robert - Bob(by), Robb(y/ie) (Scotland), Robin
Charles - Charley, Charlie (Scotland)
Edward - Ned(dy), Ted(dy) (Ireland)
A general rule - Y not IE endings unless you are Scottish
Lizzy not Lizzie, Sophy not Sophie, Charley not Charlie
IE endings were still associated with French names
As for last names - one of my personal favorite sources is cemeteries. Findagrave.com lets you browse cemeteries by location, so if your story takes place in a certain area you can go through local cemeteries and see what common names in the area were. Or just choose a random location and see if anything strikes your fancy!
