Croskell Thurnham Lancashire Area

We are looking for anyone researching the Croskell name in the Lancashire area.
My Grandmother was Margaret Croskell and her parents Alfred Croskell and Winifred Hornby emigrated to Australia in 1911, with their young family and settled at Wellingrove (Near Glen Innes NSW).
We have done a lot of research on this line.

Alfred's parents were John Croskell (1932-1910) and Margaret Ann Pennington (1835-1916). Some female ancestors names who married Croskell's include Ellen Harrison (married Joseph Croskell in 1817),and Hannah Hathornthwaite (married George Croskell in 1783)

Winifred Hornby's parents were Thomas Hornby (1843-1903) and Grace Parker (1842-1882) We go back way further. Some other female ancestors names include Bamber, Gornall, Brewer (all married Hornby's).
James Parker married Isabella Parkinson in 1835 and his father Roger Parker married Grace Cookson in 1803

It is proving difficult to find anyone researching these lines, so we would love to hear from anyone who thinks they may have a connection.
