As well as the usual BMD and census records, have you explored the parallel records kept by the canal carrying companies? There are several researchers who specialise in the records of boating families (information gleaned from watching the Waterworld series on TV). The National Waterways Museums at Ellesmere Port and Gloucester could be a starting point.
