The Admiral and Samantha's Grandmary were in love even when when she was married to Samantha's grandfather.Her husband died many years ago but she keeps refusing the Admiral's marriage proposals. Why? Is she just being loyal to her late husband? Or is it out of guilt? Plus, Grandmary seems like the type of person to marry a man for reasons other than love. It's very possible that she agreed the marry Mr. Edwards because it was the respectable thing to do and fell madly in love when she met his best friend. I can't see Grandmary ever having an affair but quietly pining for years, yes!
Uncle Gard and Cornelia are time travellersThat's why they are somewhat more forward thinking than other characters, and why Cornelia is so certain that airplanes will one day carry passengers. Uncle Gard was somehow able to travel from his own time in the early 1900s to an era a few decades in the future, fell in love with Cornelia there, and brought her and her sisters back to live with him.
All of the historical characters exist in the same universe.In addition, several of the characters are related/have met one another, due to the overlapping eras.
Julie Albright is the mother of Kailey Hopkins.Both live in California. Their resemblance is uncanny. If Kailey Hopkins was 10 years old around 2002-2003, and Julie Albright turned 10 in 1976, Julie would be around the right age to be Kailey's mother.
Kit will become a Kick-Ass foreign correspondent/spy during WWIICome on, the fanfics write themselves!
Both Kit and Molly went to movies starring the brilliant actress, Rebecca Rubin.Taking a clue from the above WMG which assumes the stories are all in the same universe. Since Rebecca, Kit and Molly have the most overlap in time periods, it's not so much of a stretch that Rebecca's acting career encompasses the two later periods.
