Hello, It seems (not checked in full detail) that there is a Merchant Seaman Master's Certificate (image seen) suggesting this chap might be the same as the one claiming to be born at Selby, Yorkshire 26th October 1825. Certificate No. 37.654 dated 16th Feby 1851 for Ibbitson Cook. When searched he also had two duplicate Certificates issued and the paperwork accompanying two of the other Certificates refers to Ibbitson Cook being in a fire / explosion. Another refers to him being on William Cook's vessel. In 1841 Ibbitson Cook 14 yrs lived at Stubbin St, Drypool, Kingston upon Hull, with William Cook (William Cook's age likely rounded to 35 years) and family.
