Great progress so far.
You seem to be getting there and if I may this is my tale, hopefully it will help.
My Paternal line was questionable having no DNA matches who I recognised. To cut a long tale down to manageable reading, DNA tests by Paternal “Cousins” revealed that they are not my Biological Cousins as suspected my Dad was not my Biological Father.
So with that I set about finding who my Biological Father was.
In my DNA matches, Neville and I share 240cM according to our Ancestry DNA tests and that puts him in the Second Cousin territory.
Neville has a family tree of him and his father who was called Samuel, that was all I had to work with.
I built a tree with Neville as the Home person and it quickly expanded to over 500 people.
Neville’s Grandfather Dominic was one of 11 children and this was the place to start as with him probably being a Second Cousin to me Neville’s Great Grandfather Guillio (Italian b1852) was probably also my Great Grandfather.
With 11 children I probably fit into one of these 11 lines so I started researching each of them and also put my DNA on My Heritage and ftDNA and from each of these I found a DNA matches who are both sharing over 100cM with me which puts them as my likely 2C1R. Each of these belong on a separate line to each other and to Neville, so that whittled the 11 lines down to 8.
WW1 came and 3 of Guillio’s 11 children were killed in active surface so we are then down to 5 lines. 1 never had children and 2 more had children but not male and the age range of them did not fit.
This gave me 2 possible lines into which I fit and looking at the 2 lines there were three males born between 1914 and 1924 so I had 3 potentials as my Father, with 2 of the 3 being Brothers and living in the Town where I was born.
Letters were written and a response gave me hope from the response I found where my probable Half Sister or Half Cousin was living so I paid her a visit.
On the first sight of each other we knew we were probable Half Siblings and when her DNA test results came in, yes we are Siblings. A year later our relationship continues to grow stronger and stronger.
We have a lot of time to make up for.
