I used the free site i2OCR to extract the text from the screenshots of Markowski's article and then I used Google to translate the text from the genealogy books referring to the Dellamare Polish family.---------------------------

The Dellamare family was mentioned also in Tarnów, a town close (80 km) to Rzeszów, where in my opinion the Chumak ancestor of O. Siryi (I-FGC22052, a branch of I-FGC22045) has lived.Piotr de Lamar has an article on the Polish Wikipedia.

It is not clear if Markowski's ancestor was descending from the French soldier named de Lamer or from the Italian noble named Dellamare and this is probably why Markowski stopped his tree at Karol de Lamer.
But it is interesting to know that at least until the 20th century there was a Polish family who was probably descending from the Italian Della Marra family of Norman origin.
