I am Esther van Rems, I have been researching the family of my children since 6 years. Part of the family is the Jewish branch Sealtiel/Saltiel/Shaltiel.
Of our Dutch family one Sealtiel moves to London in 1892; Est(h)er Joseph Sealtiel born 10-3-1851 in Amsterdam, she was married to Benjamin Abraham Messias born 20-4-1849 in Amsterdam.
With 6 remaining children (they had 9 but 3 died before emigration) Simcha/Sophie 1874, Rachel 1876-1944, Rebecca (Alice Rebecca) 1877, Abraham/Alfred 1879, Joseph 1880 and Debora/Dora 1881 they lived at 12 Dempsey Street in 1901 (found that in the 1901 Census).
In 1911 Ester lived with Alice Rebecca and Abraham/Alfred at the same adress, she was widow.
Their daughter Rachel moved back to Amsterdam, she didn't survive the war. Two of her granddaughters survived the war, but with no family left. One of them (a survivor of Bergen Belsen) wants to know if she has family left in England.
I have no idea where to start looking, I live in The Netherlands. Where could I look to find the marriages of the Messias family, where can I find births, deaths? Is there anyone that can help me how to do this online?
