Just found out that a small road I walk past in Corsham, Wilts, every day, Kinnear Close, is named after the only first class county cricketer to come from Corsham who played for Warwickshire and had one Test appearance. He actually came from the small hamlet of Pickwick which was fully absorbed into Corsham in the 1920s and is about 1000 yds from Corsham town centre.
Apologies for the delay in responding to this interesting post.
Steven Sheen's Who's Who of Warwickshire Cricket sheds more light on Septimus Kinnear. He suggests that Sep was the youngest of his family's 13 children - maybe he was the seventh son.
Steven Sheen says:
"Within a few games of making his debut Sep was struck down by an illness after a liaison with a female which required him to seek treatment in Germany at the club's expense. The resulting cure caused him to lose his hair and since that time no photo seems to have survived without him wearing his cap."
He might have played more for England but his fielding was poor - "whilst he had a safe pair of hands his throw was weak and he was slow in the field."
