Zsigmond Bertalan born in mid-1800s (died before 1910)married Ersebet Szilagyi (B. 1854 to parents Teme Szilagyi and Ersebet Csuka). They married and had at least two children, Eszter (b. 1878 married a man named Politzer) and Imre (my gr-grandfather) who was born 1/19/1875 in Erkeseru,Ecser, Pest, Hungary or Kiskereki, Bihar Megye, Hungary. Imre married a Rose Palfi (father's name Peter Palfi) sometime before 1903....Rose died around 1908. They had one son, Imre Bertalan b. 1/31/1903 in Kiskereki, Bihar Megye, Hungary. The elder Imre came to US in 1910, the younger Imre arrived in 1913 with his aunt Eszter Politzer and grandma, Ersebet Szilagyi (Widow Bertalan).
I don't know what happened to the aunt. The grandmother lived in WV with her son (elder Imre) until sometime after his death in 1935. The 1940 census finds her in Watervleit Michigan living in the Hungarian Baptists Old Folks Home until her death in 1947.
