I don't like reaching out for help because I'm the type of person who wants to learn the how-to by mainly asking for tips and tricks but I think I'm passed that point.
Very long story short:
My mom has been on and off with a few other family members searching for her grandfather for about 20+ years. I've helped here and there throughout the years but never really dived into it. 2 years ago I picked it back up because my mom had her first stroke and her physical and mental health wasn't up to the task (she works much poorly with tech now). I took a year away to specifically learn to research (for my degree non-genealogy related). 6 weeks ago I found out that I wasn't related to the great-grandfather I was told and I dove back in head first. I involved people who have not been searching for them for years to get fresh eyes and break down walls. 2 weeks in, I gave my mother her grandfather's name, and 5 weeks in, I was able to give her her great-grandmother's name and family that can be found all over Byneset, Sor-Trondelag, Norway.
The brick wall that I need some direction and help on is with my 2x great-grandfather Edward Larsen (1859-1922) and his parents. So far I can track them from England, Netherlands, and Philadelphia but I cannot seem to place him in Norway where the majority of the documents suggest he was born. The US documents that can be found suggest his mother was Jeanette Larsen (1829 or 1835) and his father was Lars/Lewis Larsen.
There are multiple leads that I've gone down such as one that was born in Orkdal, Norway to Lars and Karen however, further research suggests he's the wrong one because he marries another person and traveled to a different state in the US much more moving back to Norway.
A few other leads I followed are solely on his DOB which seems to have remained consistent however, the mother either died in Norway or has 1 or 2 children which is far from the suggested amount on her 1910 US Census.
I have my DNA uploaded to as many free sites (and some paid) as much as I possibly can and have gone through almost everyone (including very low cMs) to see if anyone's tree has something. It's especially hard when many of the matches do not have a tree built, don't provide any information, or are private (and never respond). I went as far as searching 1 specific person at a time and clicking on the profiles of people who own the tree to see if my or my cousins (I collaborate with it) DNA matched the profile. I've even built floating trees in my research tree from matches that have some information to go on and while I made some good connections, it's not to Edward Larsen.
I'm at a loss and any assistance, advice, tip, or trick anyone can provide that I haven't tried yet is greatly appreciated.
