Genealogy / Does anyone, especially descendants, have information about Antonina Suplicka Kubach/Jakubowska? [3]

Does anyone have knowledge about Antonina Suplicka Kubach? She was a sister of my great-grandfather, Frank Suplicki, and was the only member of that family to have lived her whole life in Poland (all her brothers and sisters had emigrated to the U. S. - mainly to Buffalo, N. Y. and Stevens Point, Wisconsin - in the 1870s and 1880s). She kept in contact with the families in the U. S. up to at least the 1930s. She is noted as still "living in Poland" in the obituary of her brother Jacob, who died in Wisconsin in 1932, but by 1944, when her brother Frank died, she is no longer listed. Therefore, she must have died between 1932 and 1944. I also have seen that her married name might have been Jakubowska.

She was born in Wojcin, and baptized in the church in Szczepanowo, which is near Znin, on May 21, 1866. Her parents were Joannes and Victoria (born Szymanska) Suplicki.

I would be very grateful to hear from any of her descendants living today in Poland.
Thank you!
