Looking for Greenspans from Siedlec, Poland

I am looking for descendants of Jacob Chaim Greenspan and his wife Shaindle (born Rutta). They lived in the town of Siedlec in Poland, and they have both died in 1929 and are buried in Warsaw. Shaindle was 65 years old when she died. I am told that they or their children have lived in London, at least for some time.

Any information on this family will be appreciated. I am a distant family relative of them.
