Lund, Merrill, Carrington

The church announced that Patrick Kearon was ordained an apostle yesterday. He was baptized on Christmas Eve 1987 at age 26, so I went looking for the last time someone baptized as an adult was later ordained an apostle. I had to look back farther than I had guessed.

Ulisses Soares was a child when his parents were baptized, and he was baptized at age 8.
Dieter Uchtdorf likewise.
John Widstoe was baptized in April 1884 at age 12.
Charles Penrose was baptized on May 14, 1850 at age 18 and ordained apostle July 7, 1904.
Anthon Lund was baptized about 1856 at age 12.
Marriner Merrill was baptized April 1852 at age 19 and ordained apostle October 7, 1889.
Albert Carrington was baptized July 18, 1841 at age 28 and ordained apostle July 3, 1870.

So, the last apostle prior to Elder Kearon to be baptized at age 20 or older was someone born in 1813, when Joseph Smith was seven.
