Carolyn and list-- The reason I asked about glassblowing pre-1836 is because 1836 is the first record (so far) for my Donegal emigrant Connell HARLEY in the US (it's when he gets married in Philadelphia). So, if his son Hugh learned glassblowing from an uncle (Connell was not a glassblower), the uncle would have had to have learned the trade in Ireland prior to c. 1836 -- assuming Connell and this unknown brother emigrated at about the same time. But writing that makes me realize I'm making a big assumption. I haven't identified all Connell's siblings yet, and haven't found emigration dates for any of the ones I do know (I've looked -- there are no matches for Connell, and too many Marys, Hughs, Daniels, etc., to know which are mine), and it's quite likely that his siblings came over at different times. So, it's possible that some emigrated after Connell -- so the 1836 date is flexible after all. All of which makes me ask if anyone has the OS Memoir for Donegal and can see what, if anything, it says re the glassblowing industry. Thanks, Carolyn, for making me rethink my date limitation!
