Interesting, the bit via TROVE, but these days people use numbers instead of names.
Must have been a fair sized house to have the wedding reception there, but there are a few big houses on OCR (Old Cleveland Road) even now - its house numbers go nearly to 2000, it's at least 10k long though of course not all Coorparoo, but that part would be a few km at least.
My friend hasn't answered yet - must have gone away for Christmas. I'll be surprised if she doesn't know - Coorparoo house history is one of her hobbies.
