I stumbled onto this today(browsing reddit), it is somewhat like shorpy, but the scans are a bit lower res, and the site is not very fast, nonetheless it is a very cool collection of about 200 5x7 dry plate negatives from the turn of the century (1900s). Unlike shorpy, it provides an interesting and narrow ethnographic record of this family and its travels. Not all are scanned yet, so I will be bookmarking it to check for updates. I hope others find such historical images interesting too!
Just a few linked sample images from the site:
