Hi there!
I've analyzed the page, and yes, according to it's structure, results are loaded within iframe.
There is actually a little trick you can still use and successfully scrape the results, as iframe source redirects to an actual results page that's been taken to be loaded within iframe.
Here's the URL that iframe contains on a website you brought:
/searchserver/people.aspx?id=E8FDBA59-2FA3-40FD-BC5A-3A67F7253023&cdbid=&canconnect=0&canmessage=0&map=True&toggle=True&hhSearchTerms=
Then we just add it to the original hostname,
https://www.ilchiro.org/searchserver/people.aspx?id=E8FDBA59-2FA3-40FD-BC5A-3A67F7253023&cdbid=&canconnect=0&canmessage=0&map=True&toggle=True&hhSearchTerms=
The results are the same, i would recommend you to sort it by name tho.
Happy scraping!
