As to "plug ins", I do not know. But I do know that if you have one of the commercial family genealogy softwares, it is a simple matter to read what you download as GED files. All you have to do is to download them to the file of your choice (make up one), then go into the software [i.e., genealogy] program, click on" import" [probably under "file"], name the file and path you downloaded it into, maybe give it a name and hit "go" or "enter" or "ok", whatever the program says. This puts the downloaded info into your software's configuration of families, etc.. I've done this successfully many times. Lots of luck
