Flickr would meet your requirements (I'm sure there are others). With respect to:
- Recognize Lightroom face tags and allow searching on them
When you identify a face in LR, the information gets recorded two ways, as a name attached to a rectangle around the face, and as a regular keyword with that name. Flickr will display the person keywords assigned by LR and let you search them, but it won't display the face rectangles.
Thanks John, I hadn't thought of Flickr even though I have a Flickr account. I tried it and it appears there is no way to limit the tag search to within one of my albums or even within a photo stream. I found a bit of a work around but this would be challenging for some of my family members!

That's too bad. You are able to limit a search to your own photostream or your contacts' photostreams. So if family members wanted to search, the could create an account, add you as a contact, and then limit their searches to their contacts. Not a great solution, but perhaps workable.
I had used Flickr about 5 years to do a similar family project. It had a lot more features back then, and it worked out well. But Flickr has struggled to keep up with its competition, has thrashed a lot with its redesign, and generally doesn't really know who they want as a customer and why. I've moved move own personal use to Zenfolio (but it doesn't have the searching you're looking for either).
