I have searched years for something on my gggrandmother. She married under the surname of Mary Barlow (m.cert shows she was a widow and of full age). At the time of her marriage living at 14 Stafford Place, Pimlico. London. Her father is shown as John Hall – Fisherman. From this I assume her maiden name to be “Hall”. She married my gggrandfather James Slark who was a “Groom to Her Majesty” and at the time of the marriage was living in the Royal Mews, Pimlico. London. Marriage 7 February 1842. Mary brought a 3 yr old son into the marriage by the name of Charles Barlow. I believe I have found a baptism record dated 10 July 1808 in Wokingham, Berks. I have never found her on the 1841 census but on the 1851 census, she shows her birthplace as Windsor, Berks and age to be 40. The only previous marriage for her under the name “Barlow” I have ever been able to find is: 20 Apr 1829 at Eton Buckingham England to a Benjamin Barlow. If there is anyone out there that can shed any light or direction for me to go I would appreciate it very much.
