Webpage Not Appearing on Google

Site URL: https://www.siloamspringsmuseum.com/

I have been struggling to get my webpage to appear on Google for about a couple of months now. I started working at a local history museum a few months ago. They had already created a webpage using Squarespace, but wanted a fresher look and some updates. The website never had issues with being discoverable until I chose a new template and launched it. 

I've tried multiple routes, such as making sure the indexing by Google button was on, claiming a sitemap via Google, making sure my website domain (done through a third party) was connected and up-to-date, and so on. No matter what I've done or changed, it still is not discoverable.

Can anyone give advice on how to fix this? Here is the website link:
