Hi Geoff,
I have just come across your post and think we have the same Joseph Burkett on our family trees.
My Joseph is son of Thomas Burkett and Elizabeth Blaskett, Lydd. He is one of ten children (two of which died as infants). My 4x great grandfather George Burkett is his brother.
In my notes it says Joseph was a Tailor. He managed his brother George's business at Dover after his fathers death. In his burial entry he is stated to be of Kensington where he probably lived in his old age with one of his prosperous sons.
His wife was only named as Harriet? and their children are Jospeh Frederick, Josiah Bradshaw, Lawrence Jospehus, William, Thomas, Frank, Harriet Amelia & Harriet Amelia (both died as infants).
I can see from my notes that Joseph Frederick was in the Royal Navy and was later the coastguard at Dover.
If this all looks familiar I would love to hear from you, as this branch of our tree is very incomplete.
Kind Regards
Jo
