Hi, Pete - I know of another rural county in PA where there are two local online newspapers (I think they are online versions of local publications). They do have an obituary section - but they do nothing whatsoever with marriages and births. I would think this would bring loads of out of area traffic to an online newspaper - especially if there were pics. I don't know if there is an online newspaper which offers this???
There are various options you can consider to manage the site - from Cornell's Athenagold to the ones mentioned - or even Joomla. It depends on your budget
While I think about it, the newspapers I mentioned above supplement their content by importing newsfeeds from online news services, so there is an element of current national and international news and business information. Current local weather as well - plus, no doubt, a good sports section.
You'll be busy
Best
