Is Samuel Monroe, b 1776-1779 Port Tobacco, MD really the son of John William Monroe of Fairfield, Conn?

Question

My parental third great grandfather is Samuel Monroe b. 1776-1779 Port Tobacco, MD. Dozens of on line genealogies give his father as John William Monroe of Fairfield, Conn. However in over 50 years of research I have not been able to find one line that gives any source or one single piece of documented evidence of this parentage! You site lists three individuals who it says might confirm a relationship to John William. They are Richard Monroe  --  Mito YDNA # T11385, Stuart Monroe  --  Mito YDNA # T13819, and Ron Monroe  --  Mito YDNA # T176218. My Mito YDNA # is T14385. My understanding is that if they and I all have matching Mito YDNA numbers to John William and that if we are all direct male descendants of John William, then  Samuel has to be his son. I have tried to compare my Mito YDNA number to each of the above but I cannot understand what he results mean. This should not be rocket science and this may be a stupid question but at 91 my eyesight does not allow me to wade through your learning curve so I don't know what these comparisons tell me or even if they can answer my dilemma. There must be some way to answer this parentage problem. Can you help me resolve this?

I added a tag for dna.

Is this the Profile for John William Monroe mentioned above? https://www.wikitree.com/wiki/Monroe-3376

Common sense tells me this is a mistake. If Samuel was born in Maryland, he couldn't have been the son of a man who lived in Connecticut. Was he born in Maryland?

Have any of the descendants of John Monroe of Conn taken a Y DNA test? If so, do you share Y DNA with them? If https://www.wikitree.com/wiki/Monroe-3376 is who you are asking about, then... No, he is not Samuel's father because his descendants are not part of your haplogroup.

Yes, https://www.wikitree.com.wiki/Monroe-3386 is about whom I am speaking and is the John claimed on so many lines to be Samuel's father. If 1776 is indeed Samuel's correct birth date he would have been 14 in the 1790 census of the commonwealth  of Maryland , assuming the family had not moved. There are less than a dozen Monroe heads of household in that census and I can only find one with a male of that age that fits. That family is one of a John Monroe living in Port Tobacco with a Thomas Monroe on the next census line. So Samuel's  father most certainly is "John" but not that of Fairfield. Since the line of John of Fairfield line may go back hundreds of years to Ireland it would be most attractive to add to ones family tree. I presume  that early on someone claimed it to be correct with dozens later taking their word and adopting that parentage as Gospel Grrrr! That practice has cost me 54 years and hundreds of hours. In my ignorance I did not realize different haplogroups was proof that John Monroe of Fairfield was not Samuel's father. At least that confirms my suspicions.

The question remains who is the John Monroe that certainly is Samuel's father. I have found evidence of several Monroe families in Maryland in the late 1600's to mid 1700's but there is a time gap between that and the birth of Samuel's father who must have been born ca 1754 to establish any connection. Hopefully someone who reads this has some information to end my years of frustration.

You have a Big Y match that claims Samuel Monroe 1702-1760 as his MDKA. Your common ancestor with him was born about 1673 according to your Big Y tests. The birth of this common ancestor could easily be in the early 1700s.

See: https://discover.familytreedna.com/groups/munro-dna/tree?subgroups=79080

So... Samuel Monroe 1702 could be the father or grandfather of Samuel Monroe 1776.

Have you investigated your match's family tree?

So how can I research Samuel 1702, please?

---

Log into your FTDNA account and click on your Y DNA Matches. If your match has a tree attached to his test, the Tree Icon will be Blue and you can click on the Icon to see their tree. If they do not have a tree try contacting them and asking if they would be willing to share their research. You can find their email address by clicking on their name on the Y DNA match page.

Even if they have a tree, you should probably contact all of your Big Y Monro(e) matches and ask them to share their research with you.

Best of luck,

Russ

On the Time Tree from your haplogroup, R-A21174, who FTDNA says was born about 1673, might be Samuel Monroe 1702. 

You and Munro (Morgan Monro b. 1800) apparently share Samuel Monroe (represented as R-FT252159 on the Time Tree) as your common ancestor.  

Monroe #635203 (Samuel Monroe b. 1702 d. 1760) and another guy who has his privacy level maxed out share a common ancestor born about 1830. 

In your Y DNA matches, the guy with the privacy levels maxed out may be visible to you. He will be the other match that has R-FT177648 as his haplogroup.
