Who were you??

Good Evening to all..
As many of you might know my name is Gemma. What u might not know is i am the daughter of Jack and Rosemary. Granddaughter of Sebrial and Jack. GREAT granddaughter of Nena and James. Where am i headed you may ask? Well lets start at the beinging roughly 46 years ago.
My grandmother met a man named jack and later fell with child. With already having one child to a different man this was highly frowned apon, and wore a girdle for as long as she could to hide this. 9months later on the side of the road between Fifeild (google it. Middle of no where) and the nearest hospital out popped my dad :) .
Why not just ask my grandmother u may ask. She passed in the may of 1987 the year before i was born.
Grandma then went on to marry Ron (who we only refer to as ron or him! As he has nothing to do with me in 22years. Not even a hello is exchanged at family dos on his behalf. ) they went on to have 4 more children 2 boys and 2 girls (whom i love dearly)
Back to point. Dad remembers a man sitting in the stands watchin him play football as a child and teenager. This man was his father! Jack. Y they never met is still a mystery to us.
As we jump forward roughly 35 years. One rainy sunday we receive a phone call i was bout 15 at the time. It was a lady from canowndra. Anne was her name. She said she was jack's cousin. She had rang to invite us to a family reunion. ( in which dad declined - do you blame him? ) she went on to inform dad that Jack had passed 2 years prior. But out there he had a sister and a brother. Whom he had no idea bout. And that was it we haven heard from her since.
And this is where i come in. Im now 22 and am searching for my family. My aunty and uncle . My grandfather. Whether or not he has passed ( can not find a notice anywhere.). Who he was? Where he was born? What he did for a living. Im not after any thing just knowledge. Maybe a photo or 2. ( dad is ment to be a spitting image of him ). I guess i am trying to find where i fit in. I dont look like any1 and no im not adopted. Ha ha ha.
So i am putting it out there in the blogsphere hoping one day this will fall into the right hands as my google search has hit a brick wall. A big brick wall. Maybe one day i will find where i belong. Maybe one day i will meet those i would like to call family.
