Well, yeah, personally I wouldn't want a mummy in my house! Yuck!

However ... despite the fact that it is a whole body, is there really a lot of difference in keeping it in the house and people who keep relatives' cremated ashes in urns, boxes, etc. in their houses? It's obviously less shocking to see a urn full of ashes than a mummified body ... but isn't it really sort of the same thing?

Mummies were "all the rage" in the early twentieth century, when most of the excavation of Egyptian tombs took place. Many well-to-do English folks had a mummy or two around the parlor as conversation pieces, and to show their connection with the archeological "in-crowd". I read somewhere that mummies of commoners were so, well ... common, that they were sometimes used as tinder in fireplaces. Disrespectful and sad but true.

It was probably just one of those things that generation after generation of this family just knew about and grew up with all their lives. Maybe things don't seem as weird to you if you and your entire family have known about them and accepted them for generations. I do, however, think keeping it in obvious open display and putting picture of it on the internet is in EXTREMELY bad taste.
