Hi
Agnes Robertson Mc Millan was my Grandmother. My Great Grandfather was William Mc Millan. I see both are being searched for on this site. Agnes was married to Alexander, whose death I have recently found in Commonwealth War Graves. He died at Le Havre on 8 September 1917 and there is a head stone in the Ste Marie cemetary in Le Havre, France. He was Master of the SS King Edward. I am waiting until the National Archives at Kew reopens to get the ships log and see how he died, if recorded.
Agnes R Mc Millan and he had a blazing row before his last known voyage and before his second daughter, Margaret (who went onto great things) was born in 1910. He left, never to return and Agnes had to leave her children with relatives and go to Liverpool to find work and support the family. My mother was told he was lost at sea - however - his grave record and probate shows that he was living with a Sarah Carmichael, (known as McKellar) at Greenock, and she put the inscription on his grave and was also awarded his estate (£703) worth about £50K as of 2021, rather than his legal wife.
I remember the Bygrave relatives - we used to visit them in Liverpool from time to time. There was a great mystery about this, which was only revealed later, after grandmother's death.
I have only recently started to research my Mother's side of the family - I'm looking forward to the 1921 census being released, as it may answer some questions. KB
