I haven’t seen any lion family crypts in the US (yet), but that doesn’t mean they don’t exist.
This one commemorating the Bostock family is located in Abney Park, London. Click on the photo to enlarge it, and check out the inscriptions on both the front and side of the base. Don’t forget to look through the weeds at the base of the crypt where the Bostock children are listed.
Not sure why the wife’s name is emblazoned lengthwise across the memorial while the husband, who appears to have died before the wife, is relegated to a side carving. Thoughts, anyone?
