Unless you count the episode in The Adventures of Sonic the Hedgehog where Sonic dresses up as Eggman's love interest and almost gets married to him. But of course Sonic sabotaged the wedding before they were actually married.
No, Dr.Eggman created Shadow the Hedgehog. Sonic had real parents.

It seemed that SEGA and Archie decided that those 2 should be together. So later in the stories Sonic and Sally got married
In the Archie comics, Sonic married Sally Acorn (princess of Mobius) and became the king but to a turn of events Sonic had to leave to fix a tear in time and when he got back the timeline or the present had been altered. And Shadow had taken the thrown and married Sally. Then Sonic made a plan to overthrow Shadow. Sonic, Tails (Miles Prower), and Lara-su (Knuckles' daughter) fought shadow and reunited Sonic and Sally returning things to the way they were
he got many forms e.g. super sonic, dark sonic, dark spine sonic
Sonic the Hedgehog got his name from his grandfathers ( Later on his name was changed to "sonic".)
