The start of all of them are universal and definately read "Will" ~ it is the end bit which is questionable!
I agree the 1st one (Harriett's) looks more like Williamson,
But I do think her father is John William Williams.
Perhaps Chris1066 could give his take on this one also?
For future reference click "additional options" underneath when you are posting. here you will be able to attach jpegs. etc. Hope this information helps you
Also to find out you could also search for a John William Williams or Williamson in the 1861 Census for the region to find out
