You don't need to visit Birkenhead to ask questions of the Archives and Register Office.
They both have email addresses, so in fact you could use the 'email/IM' link in Photobucket to send them your copy of the certificate.

And if you want to know what places and streets look like nowadays there's sites such as google maps. Replace the usual www with the word maps in front of google co uk. (We're not allowed to post direct links to commercial sites, hence my not-entirely-precise URL. I'm sure you can work out where to put the dots. )
Do be prepared to be a little disappointed as you 'walk' along the streets as they ain't what they used to be in many cases.
