I'm sorry if I appear to be bludgeoning things a little but you appear to be jumping to conclusions based on other people's faulty research.
For certain you know that your ancestor was Emma Smith who married Samuel Price. From that point onwards you seem to be looking at other people's trees and trying to make it fit. However because their info is wrong you can't.
The marriage you mention between Charles Smith & Elizabeth Morgan (which Janice found from info you provided) is correct but you haven't confirmed the connection between Emma and that Charles & Elizabeth - again because there isn't one.
I don't like to advise people to spend money on certificates but in this instance it is probably the only way forward. So whilst their marriage record isn't online you can purchase their marriage certificate from the GRO. I suspect that this will confirm that Emma's father was Charles Smith the Glass Worker but even it doesn't the info it provides will help you make that next step back.
Below is the link to the GRO, where you can order it online (£12.50). You have to register but the ordering process is straightforward...
