lissa,
Thank you for the time you have spent trying to help me
As you can probably tell, I am new to this research & learning the hard way as usual. Early on, I would spend hours searching through different on-line lists & not keeping track of the results. I found a Joseph on an immigration list that seemed to be a possibility. The spelling was way off but I remember he had an occupation of hurdle maker. This was before I found out for certain that this was indeed my great, grandfather's occupation so I didn't bookmark the find & now I can't find it again

I know I have checked the ancestry.com immigration sources. Beyond that, I'm not exactly sure what I've checked or not checked at this point. I'm not familiar w/ all of the sources you mentioned? Is there one site that has links to all of them? As you mentioned, all of the different spellings of Studley / Stoodley is adding a level of difficulty to the search.
Any advice you have on how to proceed would be much appreciated!
Cecilia
