Welcome to WikiTree! I tried looking up some names you mentioned on WikiTree to see if I could get you some quick help. There are several but I don't think they are the correct ones.
Here is what you can do easily: Google: Wikitree Daniel Spencer (or any name you want to see if they are profiled here)
That being said, WikiTree will ask that you start entering your pedigree (family line) then upgrade to a Family Member and then sign the Honor Code! It is all Free!
Your first goal is to get your family entered in, grandparents on all sides as far back as you can! When we see some birth and death dates associated with the names, we can start searching.
Your second goal is to try to connect your ancestors to the big tree in the illustration. That will happen when one of your ancestors merges with a person already profiled here. It might be a distant cousin of yours who relates to the same person so that they made a profile already. Once you get connected, so many amazing things you will discover! Like: Presidents, Movie Stars, Mayflower Passengers, Kings and Queens and distant cousins who you are related to.
Thank you for introducing yourself! This is the place to come to for help! I have only been here two years and when I started I knew nothing about genealogy or how to find sources. The members here were very kind to help me! Stick around because you are about to discover some amazaing stuff!
