What I fed back about Sarah was ignored by loads of posts giving personal opinions on the Likeness of the Two.
To give you info you may already know.
Sarah Junner living on Skye was appointed Nanny/ Governess of 4 Daughters in County West Meath Household of Sir Thomas Chapman it was not long before the Nanny became a Mummy and gave birth in Dublin to their first illegitimate son Robert. She became Pregnant again and Lady Chapman found out , unable to Divorce, Sir Thomas Chapman left his Wife and 4 Daughters and Estate and eloped with Sarah to Porthmadog where they lived as Mr & Mrs Lawrence her presumed Fathers name ,she gave birth 1 mile away at Tremadoc to T E Lawrence and 3 other sons.
In 1919 when Sir Thomas died in Oxford of the Spanish Flu , She and Robert went to China as Missionaries from 1919 to 1935 when T.E. died they arrived back after the Funeral probably very thin after living with the poor.for 16 years. They lived with Lady Kennett widow of Scott of the Antarctic who had sketched Lawrence in 1922 and Sculptured many Busts. She may have had an Artist Friend C C Shaw whom she invited to her home to sketch Sarah can't discount that.
But Sarah would unlikely have filled out in the face in 7 years between 1935 and 1942 when her diet of 16 years previous was already established.
And the Left Colour Painting of her in 1936 shows her thin and drawn as she was at her Death in the 1960's
Furthermore she hated the name Shaw which her Son chose at random to avoid rotas when he rejoined the RAF in 1922 and legally changed by Deed Poll in 1927 and died as T E Shaw in 1935 but his Mother refused to accept that and had on his Headstone TE Lawrence inscribed although his Birth Name not his real name of TE Chapman same as mine.
