Lizzie's hair is historically incorrect. She wears it in loose curls and has her photograph taken with her hair down. No woman in 1863 would wear loose curls or be photographed with her hair down. Hairstyles for women in the time period wore hair severely parted in the middle, draped over the ears in order to hide most of the ear except a small part of the earlobe, and fastened in the back of the head in a knot, either smooth or braided. All young women who were eligible for marriage and certainly married women wore their hair up.

In the video game Scottie is working on, General Stuart (as in JEB) is misspelled as Stewart.

The antique desk was transported by Scottie to his home upside down on top of his SUV. However, when the secret compartment was first opened, the pen and the ink bottle were perfectly in place, and they evidently had not bounced around at all in transit or they surely would have been heard rattling around.

Since at least a month had gone by in the 20th century during Scotty's coma, the trees (indicating autumn) should have had more leaves on the ground

The trees surrounding the house should have been much smaller in the 19th century (or larger in the 20th)

The historic 1 cent stamps used in the correspondences would cost Scottie $17500. in 2014 funds making these love letters a very expensive endeavor for Scottie.

A contemporary "Chessie System" caboose can be seen in the background of one flashback scene at the railroad station.

The first shot of the Whitcomb house in 1863 has a small electric light on over the front doorway.

The red umbrella Lizzie carries in Boston is of modern design and manufacture.
