Jacob Domb Sarah Domb

Looking for more info on Jacob Domb born in Lodz, Russia born about 1869.
Some of the info I do have states that Jacob was born 1872 but also married to Sarah in 1872.

I trying to find who Jacob's parents were & of any brothers/sisters he may have had in Russia b4 they moved to London, England & then New Zealand in 1905.

If any1 has any more info I would like to hear frm u.

I think with sum otha info I have is that Sarah who Sarah Harris from Lodz, Russia, born about 1861 b4 she married Jacob Domb in 1872.
