Help needed please

I would greatly appreciate any help or guidance to help me to continue my research into my family tree.

William Douglas Sheard – My Father

William Douglas Sheard, born in Liverpool 20 th July 1934 and Died December 2004 in Flintshire, North Wales. My father had a brother Clifford James Sheard who was also born in Liverpool in 1939. Clifford went onto marry a Jean F Crennell in 1960 in Liverpool. My father’s parents were William J L Sheard and Edith Elizabeth Baillie – both born in Liverpool

William J L Sheard – My Grandfather

William J L Sheard was born in Liverpool on the 8th August 1912 and died I think in 1980. His father was a William L Sheard and his mother’s maiden names was Doherty and her Christian names may have been Margaret Jane.

William J L Sheard was married twice. The first marriage was to my grandmother Edith Elizabeth Baillie in Emmanuel Church Liverpool in 1932. William J L Sheard later remarried a Lillian Llewellyn in 1953 again in Liverpool – there were two children from this marriage but unfortunately I have no details

Edith Elizabeth Baillie – My grandmother

Edith Elizabeth Baillie was born in 1913 and the birth was registered in West Derby Liverpool..

William L Sheard – My Great Grandfather

I am on really shaky ground here. I believe my great grandfather came over from the Isle of Man. He married my great grandmother Margaret J (possibly Jane) Doherty in St James the less in 1909. I have managed to find a William L Sheard on the 1891 census on the Isle of Man visiting a Esther Sheard who was a widow aged 32 and working as a servant for Thomas Quick at what I think to be Cronk ne vessage

Regards

Douglas
