I don't know if the Peru Lodge is still active, but the Odd Fellows (IOOF, Independent
Order of Odd Fellows] is still active in Indiana, though there's nothing at the web
address you get by googling the state IOOF. I did find this page that lists an email
address for the state secretary, who might be able to help you.

You could also check a Peru telephone book for Odd Fellows Lodge or IOOF Lodge, although
most of the time there wouldn't be anyone at the number.
My father was active in the IOOF lodge in Rochester, in the county just north of Miami
County. They asked me to be present when they gave him his 50-year membership pin about
ten years ago. I was 53 at the time, and the members of my age were referred to as
"the young guys."
