It's always a good idea to ask for help here, it's one of the best benefits of the site.
Specifically, as you work through a lineage, if you can't find records that prove relationships, write up a post that includes what you *do* know, and what you're looking for. Best records to search for are not only the obvious ones (birth, marriage, death) but also the more obscure such as deeds, probate, guardianship and church or town records. If you find a death record, search for probate. If you find a residence, search for deeds/land records in that area.
If you can't find a record, or don't know how - ask!
