Repeated use of the same source in the same profile
Here's how to use the same source citation multiple times. The first time you use it, include a "name" inside the ref tag, like this:
<ref name="birth certificate">Birth Certificate of George Russell Beebe, Registration 398-5554-428 (1920), Missouri Department of Health and Senior Services - Bureau of Vital Records, Personal copy in the files of [[Beebe-655|Barbara Beebe]]</ref>
In all following references you can just use this:
<ref name="birth certificate" />
Done this way, all subsequent footnotes for this same source will point to the same footnote at the bottom of the page.
