If Salamon born ca 1860, he would only have been 13 years old when Isaac (1st listed child) is born. I have Isaac born 2 Dec 1873 and sister Ester (you have Mariana) born 1877-78. If Isaac was the first born child and father was 17 years old at the time of birth, then Salamon would have been born 1856. If, however, Ester was the last child born and father was 50 years old, then he would have been born as early as 1828. I think it would be more correct to estimate Salamon's birth at 1828-1856. Same for his wife.
