It looks like you are doing a good job adding your family branch profiles to the tree. When you are adding them, if your information is correct, you should see suggestions for possible duplicates already in the tree. If so, you should be using those suggestions if they are a match. Remember, there should only be one profile in the entire tree for each person. If you are not seeing any possible duplicates, it means you have not yet connected to the greater tree. This is ok, as it means you branch has not yet been added and if it eventually connects you will have provided a missing branch.
Now I also see that you are adding profiles but have not provided any source information. It is extremely helpful and necessary to have source information so others can verify that your information is correct. Having correct information will help you and others find a true connection.

Just keep adding what you know and what sources that support what you know. With luck, you will eventually make a connection.
