which was given me VS which was given to me

Google Ngrams suggests that with passive give the bare objective was greatly preferred throughout the 19th century, but was also in steady if slow decline. The crossover (the 100% line) on the graph) occurred in the 1960s, in both AmE and BrE. But it cannot be said that the bare objective is 'confined to the novels of Jane Austen': the examples given show a current incidence 40%-70% of the incidence of the corresponding prepositional datives, and in fact the prepositional uses seem to be experiencing a modest recrudescence.

There are strong regional differences in Britain. 'Please give it me' or 'give it me back' is extensively (almost universally) used in parts of the north of England, especially Lancashire and Yorkshire. (I'm not sure about Geordies. If there are any reading please confirm). In fact it forms part of what might be described as the 'Northern British Standard'.

Down South we say 'Please give it to me'.
