Found a reord on FindMyPast for Henry Marshall, born 1814 Shields - one of the ships looks like the Jenny, 1835 voyage. 1835 Lloyds has a Jenny, 82 tons (my earlier effort at Jessy?). His other ships as Captain, 1835-1837, look like Cumberland, Alpha, Salus, Thames (these records often hard to read)
That's interesting, I have found it on FindMyPast. Do you know what the numbers mean? (e.g. for Cumberland it has "Feb '38 75/171")
Thanks for the link to the research guide also! 
That's what the link is for -eg "75/171" identifies the ports sailed from/sailed to. Check the list.
