I did a lot of my family history 20+ years ago when you did indeed have to sit in libraries ferreting through microfiches, consulting local directories and parish records and visiting far away local records offices and Kew where you got to handle enormous old tomes listing births, deaths and marriages.
I am descended from two slightly unusual names (Irish and Kent UK) and I just tried asking GoogleAI and Chatgpt and what I got was references from the usual organisations who have been out there for years, Ancestry, Find My Past and so on. I don't want to put people off and I'd be interested to see the first set of questions inserted in the AI search.
There are many concerns about misinformation now and something that began to happen as records were digitised is that people rushed to grab at names and dates without checking for accuracy or understanding that records were often falsified, names would be repeated in families through ancestral lines so you had to be clear who you were referring to and names would also be interchangeable, first name as well as surname might be changed in everyday parlance and repeated in the records.
I spent time chasing a chap called Moses who I thought had a brother called Aidan only to discover that they were one and the same. Similarly, both surnames in my ancestry have multiple spellings with small variations - a is inserted instead of o and the (Irish) suffix is ...henry or ...harris. I'm sure we all know about the connection between previous occupation and surname. Digital records are only as good as the person who transcribed the original record and then uploaded it to a database.
