“praying you that you will come when my Lady Rochford is here.”
It would be their undoing.
History tells us that Thomas Culpepper was born in 1514 the son of Alexander Colepeper. If this is the case then he had an older brother also called Thomas (to have a sibling of the same name is not unusual) who was born in 1501. This Thomas Colepeper was married to my 13th great-grandmother's sister and is mentioned in his father's will and other Colepeper wills.
These predates the Catherine Howard affair, it seems strange that there is no reference to the Thomas who died that day.
