Tatsuaki was the great-grandson of Date Masamune, and was especially favoured by shōgun Tokugawa Tsunayoshi, and despite his tozama status enjoyed many of the privileges accorded to a fudai daimyō.
As commemorated in the story of the Chūshingura, Asano Naganori was invited to commit seppuku while being held under house arrest at the Tamura's Edo residence over the incident at the Matsu no Ōrōka in Edo Castle where he drew his sword against Kira Yoshinaka.
During the Bakumatsu period, an Ichinoseki doctor was influential in the establishment of a medical school in Sendai in 1822.
Under the new Meiji government, he and his son, Tamura Takaaki, the final daimyō of Ichinoseki Domain was given the kazoku peerage titles of shishaku (viscount).
He underwent the genpuku ceremony in 1660 and was received in formal audience by shōgun Tokugawa Ietsuna, who confirmed him as heir to Iwanuma.
In 1701, in the aftermath of the famous Chūshingura incident, he was assigned custody of Asano Naganori, who later committed seppuku at the Ichinoseki Domain's residence in Edo.
He died in 1727 at the age of 58 after an uneventful tenure, and his grave is at the clan mortuary temple of Shoun-ji in Ichinoseki.
In October, 1726 he was adopted as heir to Ichinoseki Domain by Tamura Nobuaki, and became daimyō on the latter's death the following year.
He had an uneventful tenure, which is fortunate as contemporary records indicate that he spent most his time at falconry and hunting.
At the time of his death at the age of 49 in 1755, he had only a young daughter, so the fifth son of Date Yoshimura, daimyō of Sendai Domain was posthumously adopted as his successor.
Murataka was the 5th son of Date Yoshimura, daimyō of Sendai Domain and was born in Aoba Castle.
In May 1752, he was adopted as heir to Ichinoseki Domain by Tamura Muraaki, and became daimyō on the latter's death in September 1755.
In 1756, his young nephew Date Shigemura became daimyō of Sendai, and Murataka was appointed to act as guardian.
In 1796, an O-ie-sodo erupted in Sendai Domain following the sudden death of Date Narimura and quick action on part of Tamura Murasuke in closing off the highways in the area prevented the violence from spilling over into Ichinoseki.
Kuniaki was the younger son of Tamura Muneaki and was born at the clan's nakayashiki in Edo.
He became daimyō on the death of his father in 1827, and was received in formal audience by shōgun Tokugawa Ienari in 1828.
The domain continued to suffer from repeated crop failures, and financial problems during his tenure.
On his death at the age of 25, he was childless, and his younger brother was posthumously adopted to maintain the family line.
Kuniyuki was the fourth son of Tamura Muneaki and was initially named Akichika (顕允).
Regarded as an able ruler, he died at the age of 38 and his grave is at the clan temple of Tōzen-ji, in Tamanawa, Tokyo.
However, Yukiaki died at the age of 18 at the Date clan's Edo residence, and thus did not become daimyō of Sendai.
In 1868, he obeyed the call of Sendai Domain, and led Ichinoseki troops into the Ōuetsu Reppan Dōmei against the new Meiji government in the Boshin War.
Takaaki was the ninth son of Ishikawa Yoshimitsu, a hatamoto from a cadet line of the Date clan of Sendai Domain.
On his death at the age of 65 in 1922, the titles passed to Kuniyoshi's son, Tamura Hiroaki (1875–1945), a career naval officer in the Imperial Japanese Navy.
