This is it .... The fathers surname was often given as a middle name,
Which had me chasing a Mr Marshall for years to no avail.. .. fed up now -- sure I will not find him..
I have found that the person involved
My GG Grandfather who was born illegitimately in 1835 Brixworth.... was given the name Annis Marshall Green........ by his mother.
She later went on to marry and did ok for herself.. they were in touch - although he never seemed to live with her. Although he seems to have carried her pic with him for everish... it has been restored on here in the past and its wow.....

He eventually changed his name to that of Charles Annis Green.
NOW Her Father was William -- AND I have a DNA match with HIS family..

... that is good, only discovered it last night.. So on to Mr Marshall yet again.. maybe.. ON his marriage cert my GG fibbed about his Daddy (I presume) As he said he was A SURGEON called Thomas Green.. out of the blue or TRUE doubt I will know.
Then My Patricks are NOT my Patricks (as far as I can tell checking DNA Links) -- cannot find a single link past Fred.. and was never certain as no BC for him.. so oh dear me....
some good -- some bad.. I am a Sutherland and a Himsley and a Hellyar/ Talluck all confirmed with DNA...matches. so far .. scaryily getting there.
