When I finally discovered the Google BOOKS tab (yes, you need to click where it says More!!), a whole world opened up. Things appeared that were missed on the basic Google home search. On about page ten of the searches (how sad am I) I suddenly found a Dublin g.g.g. grandmother had been a botanist with a plant named after her - tip when searching for women you need to search for "Mrs Whatever" not just firstname and last name as lots of
references from those days are simply to the married title.
This method also produced another 19th century lady relative from Dublin who had had a book of her verses published - and luckily the whole book was found and
downloadable.
Last but not least, I discovered my naughty g.uncle had written an
autobiography under as assumed name - how obliging of him - filled in all the blanks!
Good luck with your searching - you just don't know what is out there.
