Welcome to the site. There is a very interesting book about TJH's called "Harrisons of Liverpool" by Graeme Cubbin and published by the World Ship Society/Ships in Focus Publications. 'Fraid its not cheap but could someone owe you a good Xmas pressie. Not only does in have historical records but also more personal anicdotes.
I would recomend it to anybody, no I'm not on commission.
