One of the strange things about 1840 is that we never see the father of Samantha, Roxanne, and Randall. Mr. Drew had strongly supported Lamar Trask's desire to marry Roxanne, and I imagine that when the funeral was arranged, it was have pleased him to have Trask deliver the eulogy, but Samantha vetoed it, and that was that.
I was surprised to see that Julia left her 1970 clothes so easily found after the Gerard confronted her with the earring - and surely she had heard all about how Vicky's 1967 clothes turned out to be a problem in 1795. But I guess she had confidence in her ability to face down any problems that might arise.
Why did Roxanne get put in a crypt instead of being buried?
