Given the task definition and input, reply with output. In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Caversham  is one of the older suburbs of the city of Dunedin, in New Zealand's South Island. It is sited at the western edge of the city's central plain at the mouth of the steep Caversham Valley, which rises to the saddle of Lookout Point. Major road and rail routes south lie nearby; the South Island Main Trunk railway runs through the suburb, and a bypass skirts its main retail area, connecting Dunedin's one-way street system with the Dunedin Southern Motorway. The suburb is linked by several bus routes to its neighbouring suburbs and central Dunedin.
The suburb was founded by wealthy pioneer William Henry Valpy, and its name reflects his family connections with the town of Reading, in the English county of Berkshire. Caversham grew rapidly during the Central Otago Gold Rush of the 1860s because of its location on routes south to the Otago hinterland. By the end of the 19th century, Caversham was heavily industrialised, and its population included many skilled or semi-skilled tradespeople. This, combined with the community's strong Protestant roots, led to the area's generally left-leaning political stance. Caversham's early history has been the subject of the Caversham Project, a major historical and archaeological study by the University of Otago. Caversham was a separate borough until 1904, when it was amalgamated with Dunedin city. It is currently administered as part of the city's South Dunedin ward. At a national level, it is part of the Dunedin South electorate.
Caversham is now predominantly residential, with some industrial premises in the east (notably the Hillside Railway Workshops) and a retail district centred on South Road and Hillside Road. Residents are generally of low socio-economic status. Caversham's notable buildings include the heritage listed Lisburn House and several prominent church buildings. Another landmark is the suburb's war memorial, which is the main gate of Caversham School, one of the suburb's two primary schools. Caversham also contains a special-needs school. The nearest secondary schools operate in St Clair, 1 kilometre (0.62 mi) to the south.
Caversham has strong sporting connections, and is the location of Carisbrook, until recently one of Dunedin's main sports venues. The suburb is home to the Southern Rugby Football Club, and gives its name to Caversham Football Club. Several notable sportspeople have associations with Caversham, among them Test cricketer Clarrie Grimmett and father and son rugby union administrators "Old Vic" and "Young Vic" Cavanagh. Other notable people with Caversham connections include politician Thomas Kay Sidey, architect Edmund Anscombe, and surveyor John Turnbull Thomson.
What is the last name of the cricketer who has associations with the suburb that is one of the older ones of Dunedin?
