Brenda Joyce Jerome has posted some lunacy records from Crittenden and Livingston counties on her blog. You can see them here:
Livingston Co Lunacy Record
Crittenden Co Lunacy Record
Concerning the Lyon County Inquest Book, I fast forwarded close to the end of my microfilm on Saturday, and I think I'm about half way through the records.... [at least I HOPE so!!!] I still learn more each day from reading these records. Hopefully, at the end of this project, I'll put together a useful index to these, and maybe put them all together... an ongoing project...
