Hi and welcome to rootschat,
To trace your grandfather's ancestry you need to purchase some BMD certs.
What country did Ernest marry in?
If it was my grandfather, I'd start with his marriage cert first.
The birth refs that Keyboard has given you looks good (
http://www.freebmd.org.uk/ ), you can order the certs from the England and Wales GRO
http://www.gro.gov.uk/gro/content/The birth certificate will give you his exact birth date, the place/address where he was born, and the parent's names, and occupation of the father.
With that you can then look for the parents marriage (that may or may not be be the Thomas Bloomer and Lilly Taylor ) - Their marriage cert will give you the names of the fathers of the couple and their occupations, plus witnesses. With that information you can then consult the 1911 census
http://www.1911census.co.uk/ and hopefully find them and their families - Then you go back further, step by step with certs and the 1901 to 1841 censuses.
I haven't read all of your other thread, but it seems that you have tried to "look Earnest up" on the internet and can't get back. I think the problem is that you do not have any basic hard evidence like his bmd certificates to start off with. It depends on if you want to trace him with 100% certainty, or you are just happy to guess at his heritage, - If you want to trace him back with any
certainty, you need to first start off with some]
good, solid, factual foundations such as purchasing his birth certificate from the GRO with the given refs that have been provided. Otherwise it is just guesses with very little evidence.
Without solid foundations,
It is very, very easy to go off tracing the wrong people. There is only so much the internet can do.
Kind Regards

Ps
ok, whilst typing my post, I see that you've just posted a reply and have now said you've traced to 1509 . A lot further than myself and in just a day , so perhaps I should not be giving tips.
Kind Regards
