VILNIUS, Lithuania (JTA) — At a family reunion in California in 2013, Felicita Trueblood discovered a portal to the past: a binder full of letters from her great-grandfather, a rabbi in Ukraine, from before World War II.

As exciting as the discovery was, the letters were illegible to her — until now, thanks to an artificial intelligence tool developed by Sergii Gurbych, a researcher in Lithuania who hungered for information about his own Jewish past. They unveiled a world of grief but also brought Trueblood solace, uncovering the truth about her great-grandfather’s death.

The letters, about 50 pages in total, had sat untouched for decades in her cousin’s house in Palm Springs. They were penned in Yiddish by Pavel Malisoff, Trueblood’s great-grandfather in Konotop, Ukraine — then in the Soviet Union — to his son, Trueblood’s great-uncle Solomon, who immigrated to the United States and changed his last name to Malis.

Between 1927 and 1934, the letters bridged two worlds — on one side, a father in Ukraine witnessing a community on the brink of destruction, and on the other, a son journeying from New York to California under the weight of the Great Depression. Malis died in 1985. For nearly a century, no one else had read those pages.

At the 2013 reunion, none of the living family members could decipher their ancestor’s Yiddish letters, written in Hebrew script. Trueblood, who is now 75, felt compelled to take charge of the treasure trove. She grew up in San Diego with few traces of her Jewish past. Her mother, Malisoff’s granddaughter, became a Christian Scientist before marrying her father, a non-Jewish descendant of colonial Americans. Trueblood wanted to know who her great-grandfather was and the life he inhabited, long cut off from her family memory.

“I was raised outside the Jewish community, with no day-to-day connection,” Trueblood told the Jewish Telegraphic Agency. “But I was always fascinated.”

Trueblood soon ran into obstacles. She found only a handful of translators who could help decipher the handwritten letters, and the cost of hiring them to work through the whole stack was prohibitively high.

But 13 years after inheriting the letters, she saw a Facebook post about VILNISH, a new project in Lithuania that aims to turn handwritten and historical printed texts in Yiddish and Hebrew into digital texts that can be easily searched and translated.
