If she was 70 at her 50th wedding anniversary in 1930, she would have been born in 1860.

Leah's marriage certificate says she was born in "Austria," which usually means the Austro-Hungarian Empire. Zglobnia/ (Zgłobnia Zgłobień) is in Poland now.

[father Josef]" ... took himself off to London, as Mother told us. He didn’t find his fortune there, came back to the village, and eventually emigrated to America. Meanwhile, a baby brother was born when I was about two, who did not survive." LKJ As I Remember, 1962, p.5

"It must have been two years after that [stillborn baby boy in 1883], when Mother was carrying Anna, that Papa went to America. A few months later, when Anna was about a month old, he sent us tickets for our passage by boat, steerage, taking not less than three weeks to cross over."

It is good to know your ancestry were people of some education, intelligence and refinement, according to the manner of their times and the laws of their religion. On the paternal side, Zvie Chaim and Rachel Kreinik, lived in a town (Sędziszów) larger than my village (Zgłobień). They were in the garment business (which Father really hated but wasn't trained for anything else) and once a year the sons, Nathan, Zalmon and Aaron, would take a load of finished garments to Krakow, where there was a Kirmash, a sort of Carnival and open market, to sell their stock. I remember that trip because it was the occasion also of Uncle Aaron's wedding to Tante Gittel in Krakow. Papa was in America, as I have already written, and Mama, Anna, Irving amd I were back in Europe for Mother's health. Leah Kreinick Jacobowitz, As I Remember, 1962, pp 12-13

I remember that trip because it was the occasion also of Uncle Aaron’s wedding to Tante Gittel in Krakow. Papa was in America, as I have already written, and Mama, Anna, Irving and I were back in Europe for Mother’s health.
Grandma Kreinik was a tall, slim, lively person, who held herself very straight. She adored us, made much of me because I was so much older than Anna and Irving, and had American tricks to show off, like jumping double rope and other Americanisms, which had the native children goggle eyed. Uncle Nathan, the eldest, was the only one who remained in Europe.
The trip to Krakow, as I have mentioned, was for business and Uncle Aaron’s wedding. Marriages were made by parents, and they rarely turned out wrong; divorces were almost like a legend. The wedding festivities lasted a whole week, as was customary, at the end of which the “Sheva Broches” – seventh day blessings, were pronounced. May I point out that this was a tradition of “Family Cleanliness,” a whole week’s waiting, after the marriage, with ritual bath on the 7th day, to promote healing. There were no sex diseases when this law was obeyed. There was feasting and dancing every evening, the women getting together every day for their own klatches, and altogether it was a happy time. There is an old photo of Mother and the three of us, which pictures me in the costume I wore at the wedding: a beribboned white dress with a red velvet vest trimmed with gold braid, and scalloped edges. In that costume I danced with another cousin, doing a dance called “The Krakowianka,” a sort of Virginia reel, up and down the aisle, everyone applauding us.

About Uncle Max Krantz: "While we were back in Europe, he (Uncle Max) and I took took a long walk to my other grandparents' home, about two miles away, on a very cold day in the winter. My hands froze, I was crying in distress and he picked me up and carried me on his back all the rest of the way. I was eight, he was twelve." p. 68
