According to the 1841 census, a ten year old Alexander Morten is a pupil at Amersham Grammar School near Beaconsfield.(notes:- pupils ages were rounded-up or down)

According to the 1851 census, the only possible/probable Alexander on this cenus is the 'clerk to a stockbroker', lodging at 31 Tonbridge Place in St. Pancras. His housekeeper is Sarah King. This Alexander, though, is the one stated as being born in Brighton, Sussex.

According to the 1861 census, Alexander is now married to Flora, living at 1 Elgin Crescent, Notting Hill. He has three children, Florence, Fanny and Alexander (another, Frances, was born in 1858 and died four months later). They have three servants living with them and Alexander is a member of the stock exchange.
By March 1864, his Stock Exchange Membership application stated he was now living in Langdown Crescent in Notting Hill.

According to the 1871 census, Alexander now has a fourth child, Emily (although again, another, Frederick was born in 1861, died in 1864). They live at 43 St. Julian's Road in Willesden with three domestic servants. Alexander is a stockbroker.
The London Electoral Rolls show that Alexander lived at 43 St. Julian's Road from 1871 until 1873. From 1876, he was at 48 Portsdown Road in Paddington.

According to the 1881 census, Flora is head of the household at the time of the census, she is the 'architects wife', and with all four surviving children, they live at 17 St. Oswald Street in Fulham, with a cook. Where is Alexander?
By 1885, the London Electoral Rolls reveal that Alexander George had taken over the tenancy at 17 St. Oswald Street, until at least 1892. An Alexander Morten was residing at 9 Pancras Street in Endsleigh from 1884 to 1889.

According to the 1891 census, Alexander is now living on his own means, with his wife and two daughters. Incidentally, his eldest daughter had married, had a son, Raymond, and has moved back home after her husband died, she is now a Peck. They're still living at 17 St. Oswald Street with a housemaid and a cook.
