Hi Carmel,
You can see the pedigree at the Kendal Record Office, or contact them to send you a copy of it. But it only includes the Machells of Kendal (& Skelsmergh, Whinfell, Patton, Selside, etc.), and does not include the Machells of Whitehaven, Lancashire or Crackenthorpe, so I'm not sure if it would be any help to you.
