Bare Facts: Female ~ Born est.1941 ~ Died 1983 ~ Mother Unknown ~ Father Unknown ~ Children Yakat, Kelsey, A19, A47 ~ ID Unknown

A10 was full grown when the study began. She was most likely born around 1941, but we have no idea who her mother could have been because she wasn't anywhere near another female except her probable daughters.
Her first known child is Yakat, who was probably born around 1958, making her 17 at the time. While Yakat could have been her first child, she most likely had another one which died before the study began.
For the next nine years, she traveled with Yakat, and her brother A4. During that time she most likely had another calf and it died as well-or maybe she just waited a long time between calves.
Around 1967, she gave birth to Kelsey.
When the study began, her family consisted of Yakat, Kelsey (only 6 at the time), her brother and her. Since the family was almost always with one of the other A-pods, the researchers took a long time to figure out that they were a separate pod. Also, the A4s were more difficult to study because, at least under A10's matriarchy, they were wary of boats.
The year the study began, A10 gave birth to A19. Sadly, the little calf died the same year. The first known tragedy in a family that eventually would become known for them.
The year after A19's death, Yakat gave birth to her first calf, Skagit, and A10 became a grandmother!
Four years later, Yakat had her second child, Skeena. Only three years after that, Kelsey had her first child, A41. However, this little one died within the year.
In 1983, many things happened. Yakat, Kelsey, and A10 herself all had calves. Yakat gave birth to daughter Siwiti, Kelsey gave birth to daughter Sutlej, and A10 gave birth to A47.
But not everything was happiness in 1983. When A10 and her newest calf A47 were at the rubbing beach, a whale-watching boat nearby heard shots. Concerned, the researcher on board steered the boat towards the beach. A10 showed up suddenly with A47, who was bleeding. She pushed the calf up against the boat, as though saying, "Look what's happened!"
After that winter, A10 and A47 were never seen again. A10 was 42; A47 was 1.
The matriarch lives on in her seven surviving grandchildren, her four surviving greatgrandchildren, and her two greatgreatgrandchildren. Oh yes, and her two children. She certainly left an impressive legacy.
