Hello, Illustrator,
Sorry to query this, but now do you know Charles was born in Kinsbury ? Did you take this from census info.? If so, could you please post the census year, with piece no, vol & page no so we can check.
I ask this as I do not know of a Kinsbury in Middsx, there is a Kingsbury & a Finsbury.
If Kinsbury has been mistranscibed or misread & could be Finsbury there is this birth reg in freeBMD. Finsbury would be in Clerkenwell. This was, in fact, my first thought when I saw Kinsbury, that it could be Finsbury.
Birth
John Foster
Mar ¼ 1851 Clerkenwell 3 112
