Davd Annal posed an intriguing question on Twitter asking if anyone could beat his four brothers marrying four sisters. I can.
Here's mine - in the early 19th century 6 Vollick siblings married 5 Burkholder siblings (you'll figure that out when you look below):
1826 Matthias Vollick m Catherine Burkholder
1827 Isaac Vollick m Sophia Burkholder
1830 Janine Volllick (1) md Jacob Burkholder
1831 Richard Vollick m Elizabeth Burkholder (My ancestors)
1831 Margaret Vollick m David Burkholder
1846 Eliza Vollick (2) m Jacob Burkholder
The Vollick family sometimes used the surname Follick. You can read more about the family at Isaac Van Valkenburg aka Vollick, Loyalist from New York with Butler's Rangers in Niagara
Can you match or beat mine?
