19th century
From Tardis Wiki, the free Doctor Who reference
The 19th century was very important to the Doctor. His eighth incarnation once called 19th century England to be his favourite time and place, (EDA: The Banquo Legacy) though his initial incarnation clearly preferred 18th century France. (DW: The Reign of Terror)
The dates of some events were not specifically known. The following events took place in an unknown year of the 19th century:
- Sebastiene attempted to hunt down the Tenth Doctor. (NSA: The Doctor Trap)
- Ancestors of Gwen Cooper, who shared spatial genetic multiplicity with Gwyneth, settled in the Cardiff area. (DW: The Unquiet Dead, Journey's End)
