This is a very long but interesting article about the Lair Family compiled by Bob Francis.
If you do not want to read the entire article, scroll down to the section on Charles Lair.
There you will find information about the vault along with pictures of the Lair home and
the coffins in the vault. This article does not talk about the glass in the coffins but I
know I have seen that information before. I will continue to look for it and post it if
and when I find it.
