Jim Walker was Jack Walker's brother. In May 1961, he agreed to look after the Rovers Return Inn while Jack and Annie went on the annual Whit Monday picnic in Blackpool, but his lateness almost caused the Walkers to miss their coach. As a result, he received a frosty reception from Annie.
- A second brother of Jack's, Arthur Walker, provided a similar role during his appearances in 1965 and 1969.
