I have found out today that definitely one of Ihonart/Sydney Sewells many Children, Edith (Grace) was born in September 1920 at 36 The Promenade, Seven Kings which is EXACTLY where my Father was born earlier the same Year (Feb) and this is also the address from his Father,Roberts Marriage Certificate in Sept 1919. Edith Grace's Parents are listed as Sidney Sewell (Travelling Showman) & Edith Sewell, formerly Jackson. I now know from further research that on the 1922-25 Electoral Registers that the occupants of 36 The Promenade were Sidney and CISSIE WALKER which I believe was a stage name. On another Birth Certificate for Ruby Florence born in 1914 they are living at 229 Henley Rd, Ilford and Parents listed as JOHN Sewell (a known Alias) & CECILIA Sewell, formerly Jackson. I don't know where the name 'Walker' came from, possible anther alias? I'm going to pay a visit to Redbridge Library to try and search some more records. It's all terribly complicated!
