My brother is a jr. and my husband is a II. I can tell you, my husband’s parents chose II instead of jr. because they thought it sounded classier, but it’s actually incorrect. The rule is: if the son has the full same name as the father, it is Jr. If the son has the full same name as another male relative, he’s II. If the son simply shares part of his name with another relative, father or not, he is not Jr or II, he’s named for that person.
If you want a junior it is “Todd Michael Ross Jr”. If you name him anything else, he’s not a “jr”…plain and simple.
Now if you want to name him after your husband but not have a junior you could use Todd or Michael in any way, together or not and accomplish that. I know a few people who switched the order (example: Michael Todd Ross) or just used one of the two names (like Michael T. Ross, or T. Michael Ross, or Michael “any middle name” Ross).
You could also name your son Todd Michael Ross Jr but call him Michael or Jr or even TJ as someone else suggested.
To be a junior, it has to be Todd Michael Ross, Jr. However, you can call him whatever you want. TJ, Mike, Michael, Jim (though he’ll get strange looks at that). 
My husband is a junior and goes by his middle name since his father goes by their first name. There were kids in school that were juniors, but would go by some other name entirely.
Please really think about this.
My husband was named after his father but, they called him by his middle name. Why bother naming your child a name you do not intend to use? It causes a lot of confusion on all the documents their name goes on while growing up.
We get mail that is inteded for his father but, comes to us. We are on every senior citizen mailing list…some of it’s kinda funny 
really?
you want to name him junior just because you like the name junior?
why not give him a name you actually like and then just call him junior, if you absolutely must?

My son is a junior. That means that his name is exactly like his father’s. Our son goes by a shortened version of his middle name. Actually, his middle name is Charles and we call him Chase. He didn’t realize his name wasn’t Chase until he went to school.
My brother is a junior as well. He goes by his middle name and my dad goes by the first name.
Personally, I’m not a fan of the whole Jr. thing. BUT it was important to my husband so there ya go.
My son says he will name his son the third. He will probably have all girls! =)
You have to use your husbands first and last name to be a jr. I would change the middle name and call your son by his middle name. I named my son the family name for sons in my husbands family. But I picked out my favorite name and made it his middle name. So my son goes by his middle name.
If you’re having a hard time finding a name you like, go online to see what names mean. It might make the names more likable. We chose first names we liked and then we used the middle names to name them after family members. We only use their first names to avoid confusion.
Juniors are really juniors. You can name him anything you want and call him junior, though. I think another option is to name him after a grandfather. That would be an acceptable junior as well.
Thank you moms! That really answered my question! I’m just having a hard time on finding a name I like. I keep crossing them all off! And my husband keeps on suggesting Lucifer. I’ve never like the though of naming my son after his dad. Just something that keeps roaming my mind wen I think about my due date this July 9…
THANK YOU ALL AGAIN!!!
