Bob,
I don't really think you could call Shackletons voyages the same era as the last Franklin expedition; Franklins voyage took place in the second half of the 1840s, whereas Shackleton's first experience of polar exploration was with the British National Antarctic Expedition 1901–1904, led by Scott.
In terms of time it would thus be like saying that the Second World War was in the same era as the Iraq War of 2003 …
There is a sort of link, though, in that the éminence grise behind the 1901 expedition was Sir Clements Markham, who had been a midshipman on one the first Franklin rescue missions.
A very interesting book about 19th century British exploration, both in Africa and in the Arctic and Antarctic, is Barrow's Boys by Fergus Fleming (**LINK**)
