Hi,
Baptism of William Pinkerton son of James and Margaret recorded in Farnworth (Prescot) Lancashire BT`s on 6th March, 1844
Also Baptism of Francis James Pinkerton son of James and Margaret recorded in Warrington BT`s 25th December, 1842.
William`s birth is on the GRO index for Prescot March Qtr. 1844 Reference Vol.20 Page 762.
I can`t find them on the 1851 census.
Regards,
Mo
