I believe this is the family This census was taken Jan 7 1920; Nora d 3 days later They are living with cousin Anthony BEDNARSKI? and family. 1920 Lawrence, Essex MA DOMBROSKI John 38 b Plock [b 6-24-1882 per WWI Draft] Eleanor 30 b Nirko/Nisko Peter 8 ME [b 10-19-1911; d 3-10-1973 Lynn, Essex MA]
1930 John has not remarried, it's only he & Peter in Peabody, Essex MA.
So which John are you researching? John/Nora or John/Feleska? Both Johns were born just a month apart, and both lived in Essex Co MA.
