Hello Listers Nottingham Family History Society have produced a booklet 'Boatmen, Boat Owners and Boat Builders', Record Series Vol 104. ISBN 1872776426, ISSN 0142-5099. The booklet includes: Trent Navigation Co Gauging Tables Nottinghams Canal Boat Registers Cromford Canal Permits These are only indexes, but list names, owner or master, number of boat and year. Don't know if this booklet is still available, but you could try looking on the above family history society's web page. Cost £3.85 but this was back in 1996! If anyone would like me to see if any names are there let me know. Helen
