William Hayhow, 1889, Newmarket or Dullingham

I am trying to trace ancestors from my grandfather William Hayhow who was born in Newmarket 6 July 1889.

His father's name was Israel (or possibly some other biblical name), and his mother was Helen Sinclair, a Scottish school teacher.

He had many siblings including Harold, Samuel, Ernest, Cyril, Winifred.

His family had been farmers and market gardeners around Dullingham for many generations.

Any leads would be much appreciated!

Cheers

Peter
