If you are looking for the current Sisters of Mary website, you are in the wrong place. It is at marists.net. It moved sometime in mid 2014.
While Archive.org generally is a good resource for the historical record of websites, sometimes it is better to recreate the website itself, especially if the website is of interest. Also, Archive.org is generally very slow, and has a clunky interface. So, here soon, the new-old Sisters of Mary website as historical record for the mid-teens of the 21st century. While waiting for its return, you can contact us.
