Dee was married three times and had eight children. His first wife, Katherine Constable in 1565, died in 1574 without issue. His second marriage (also childless) to an unknown woman lasted only a year until her death in 1576. From 1577 to 1601, Dee kept a sporadic diary (also referred to as his almanac), from which most of what we know of his life in that time has been gleaned. In 1578, when he was 51, he married the 23-year-old Jane Fromond, who had her own connection with the Elizabethan court as a lady in waiting to Elizabeth FitzGerald, Countess of Lincoln until she married Dee. When, in 1587, Kelley informed Dee of the angel's wish that they share wives, Jane Dee (née Fromond) was his wife at the time. Their son Theodore, born nine months later, could have been Kelley's, not Dee's.
