Hello Red Rum, William Knight Campbell,1817-1868,the solicitor/barrister,was my Gt.Gt.Grandfather.He was born Aston Tirrold,Berks. along with his sister Catherine and his brothers Henry,Robert and Thomas.He did have another brother John,but I cannot find out anything on him. He (William) ended up in Liverpool,with offices in Castle Street and Vernon Chambers,Vernon Street. You may well know all this so if you do, my apologies. Would you be so kind as to let me know any info. you are aware of please.We can compare notes and it sounds as if we may be related if you are also researching William. Good to be in touch. Best regards, David.
