No, since Ferb is Candace's and Phineas's Step Brother. Phineas and Candace have the same mum and dad though although the dad is never shown just like Ferb's real mum is never shown.
Ferb is from the Dad. Phineas and Candace are from the Mom.
No, Ferb is Phineas and Candace's step-brother. Ferb's dad married their mom.
Phineas and Candace took their mom's last name, and Ferb took his dad's last name.
I am pretty sure that Phineas' parents either got a divorce or his dad died and his mom remarried Ferb's dad. While Ferb's parents either got a divorce or his mom died and his dad remarried Phineas' mom. Phineas and Candace Flynn and Ferb Fletcher. Phineas and Candace also are not adopted by Mr. Fletcher. So as Ferb isn't adopted by Phineas and Candace's mom. *I am not 100% sure about this. It's just a hypothesis.
Ferb is Phineas' step brother and the Dad's real son. Phineas and Candace are the Mom's real kids and the Mom and Dad got married when all the kids were small. The dad's side of the family is from England and are in a couple of episodes and the mom's parents are in a couple too. The mom's parents are in the episode were they go camping.

I think she is about 30 but she is Freb's aunt and Phenias's mom cause Ferb is Phenias's dad's brother's son. He lives with his uncle cause his parents passed away or something. If u see the song "little brother" in phenias and ferb u will see ferb at about 6 years old coming to phenias's house holding the british flag.
