Howard Baker was the husband of Juno Baker and a neighbour of Lavinia Smith. He and his wife befriended Sarah Jane Smith when she arrived at Moreton Harwood in December 1981 but were reluctant to believe her claims that a coven had abducted Brendan Richards. This led Sarah Jane to mistakenly believe Howard and Juno were members of the Hecate Cult.
In 2009, Howard and Juno Baker were invited to Sarah Jane's aborted wedding with Peter Dalton, but couldn't make it because they were running a church fête that day somewhere in Gloucestershire. (PROSE: The Wedding of Sarah Jane Smith)
