ScotMum,
I am sorry if I sound curt but you do need to provide some more basic information for us to be able help you. I prompted you in my first reply but you didn’t provide enough information.
You have given us your father’s name but not your mother’s. You said: “There were a few brothers and 2 sisters that I know of.” Some names or general information on when they were born or died might help. That’s why I asked you to provide more. I asked you about the family denomination, and so on, and you didn’t answer those questions. I am trying to help but it’s a two way exercise.
What was your mother’s name? When and where did she and your father die? When were they born? Have you got their birth and marriage certificates? If you haven’t, then assuming the events are all in Scotland, the records should be on Scotlandspeople. You have to pay to view those records. There’s no free access, so we can’t look them up for you. With your parents births you should get their parents names and the date and place they married, and should then be able to go back another generation. And so on.

1911 and earlier, you will find censuses back to 1841.
I can see a Pierce Turkington death in Greenock in 1913, for example, but I have no idea if he is related to you, if you don’t tell me more about your family.
