The Frederic Anstruther 1872 is listed on the 1901 census for the Isle of Man says he was born Scotland
1911 still in Isle of Man states he was born Fife Scotland his name Frederic Elliot Anstruther
The family likes the name Elliott, eldest son George has it for a middle name, and at one point son Dominic uses the name Dominic C Elliott-Anstruther, and Gilbert has the middle initial E.
Have you looked on Scotland's People for Frederic Bennett circa 1872
Sadly, there is little coherence between what this family chose to declare on official documents and the reality.
I grew up with being told that all these siblings had been born ['on the wrong side of the blanket'] in India, fathered by a rich man who abandoned them to London poverty.
This myth seemed to them, to explained why they could not even find their own birth certificates. Well you wouldn't if you were looking under ANSTRUTHER! As good Victorians, the children were not encouraged to query the family stories even if some of them might have remembered being called BENNETTs. I have not yet found any school records.
I only found them all in 1881, living in Hanwell [next door to the RC church] when I searched MELGUND by forename only.
Any detectives out there are welcome to plunge in.
It would be grand to finally know how I got my two middle names!
