How often have uncles and nephews played together in the same Test?
And is Neil Brand the only player to captain his side on Test debut?

You're right that Ibrahim Zadran, a 22-year-old veteran of five previous Tests, presented his uncle Noor Ali Zadran, who's 35, with his first cap before the match against Sri Lanka in Colombo last Friday. The related pair then combined for an opening stand of 106 in the second innings.
Actually there are three Indian left-handers who scored Test double-centuries before Yashasvi Jaiswal joined the club with 209 against England in Visakhapatnam last week. Back in 1992-93, Vinod Kambli made two in successive Tests, and Sourav Ganguly hit 239 against Pakistan in Bengaluru in 2007. The other left-hand double-centurion - and the only other opener - was Gautam Gambhir, who made 206 against Australia in Delhi in 2008-09.
Left-hander Neil Brand was one of six new caps in South Africa's severely weakened side in the first Test against New Zealand in Mount Maunganui, which started at the weekend. The only other such instance in the last half-century (excluding teams' inaugural Tests) was in 1995, when Lee Germon skippered New Zealand on his Test debut, against India in Bangalore.
I disappeared down a blind alley for this one to start with, as my first thought was the great West Indian Clyde Walcott, who took 11 stumpings in Tests to go with 11 wickets as a bowler. And then I read the question properly! Walcott made 15 Test centuries, which means the leader with equal hundreds and stumpings is New Zealand's BJ Watling with eight of each in Tests - although only seven of his hundreds came in matches in which he was keeping wicket. Another West Indian, Jeff Dujon, made five Test centuries and also pulled off five stumpings.
The Dutch international Logan van Beek hit 136 against Central Districts at the Basin Reserve last week to help Wellington reach 281 for 8 after a sticky start. Sadly, rain meant the match was a no-result.
