Hi Joshua - welcome to the GMB.
dating by means of family genealogy is a not uncommon means of trying to assess the age of glass - unfortunately, it's often inaccurate, and memories aren't always reliable. Based on your comments of this piece passing originally from your great grandmother through to yourself, we might be led to believe this started life somewhere in the late C19 or early C20, whereas the shape and bubbles might suggest a later date.
Regret I've no idea as to the origin or age of your glass, so whilst we're waiting for someone with knowledge to help, here are just a few thoughts.
Columns of bubbles - appearing in a regular patterned appearance, is described usually as 'controlled bubble' decoration, and appears at various times in the C20, probably most commonly from the late 1930s through to the 1970s. Regret we don't offer to discuss values on the GMB - as you can imagine different people have very different ideas as to what something is worth - the best way of getting some idea of actual value is to look at on line auction sites for similar items , or view auction house catalogues. Your glass may be British in origin, but it never ceases to amaze just how widely travelled glass can be - equally your piece might have been made in Scandinavia or on the Continent.
Your pictures are too busy with distraction - the background needs to be a plain uniform neutral colour - to help with seeing just the glass. Not easy if you don't have a decent camera - some better lighting will help.
Sorry this is unhelpful - hopefully someone will have more positive ideas for you - fingers crossed.
