I have a fiber connection with 500MB download speed. Even for me, the images have a lag before loading. I searched through many records but did not find John Eldridge.
I took me a minute to figure out that the names were alphabetized by the given name, not the surname, but the records jumped from G to M, skipping over J.
I think the only way you're going to find his record is to laboriously view every single record until you find him, and to do that, you need to be on a network with at least 10MB speed, and it would be more helpful if it was 100MB or higher. Perhaps a local library might have that type of connection or a local college?
Good luck. You have a lot of drudgerous work ahead of you.
An alternative would be to contact the Libraries Tasmania and ask them to locate the actual record and forward you a copy. Kudos to them for putting these records online, but their indexing system leaves something to be desired.
I tried selecting the Sarah and then drilling down to 1835, but even then, the names were in some sort of odd order that made no sense at all. They certainly weren't in alphabetical order. When I finally found John, it brought me to the record that Marion posted, and that record doesn't include John.
