Years ago I extracted 1000s of records both from LDS films and a visit to Ragusa. They are on about 2000 FGSs in 7 thick notebooks. Wished they were typed!
If you have your lines back at least to mid-1800s I might be able to help you. Don't bother asking about more recent relatives -- everything i have is earlier than 1900. Most is 1700s or early 1800s, and some goes back to 1500s.
It is mostly Modica and Ragusa. Some Avola, Ispica and Scicli too. No other communi.
Post queries and I'll look.
I wanted to donate this collection to the FHC in SLC but they didn't want it because it wasn't typed. I hate that it is being wasted because it is a huge cache of stuff.
