There is no clear date when the disorder first appeared. Since even today it takes some sophisticated blood tests in order to diagnose hemophilia the ability to unmistakably identify it did not exist until more recent years.
As far back as the 2nd century AD however, there are references to what is believed to be hemophilia without the name "hemophilia" as we know it now. As it is customary for males of Jewish background to be circumcised, the first known reference believed to infer hemophilia comes in the form of an exemption for circumcision.
Hemophilia has been written about many times since those days and it was even recognized that the disorder followed the female side of family lineage and largely affected males.
The term "Hemophilia" was first used as a name for the disorder by a university in Zurich in 1878.

Genetic hemophilia is a life-long chronic condition. A person would have it all of their life, from birth to death. Acquired hemophilia happens as a result of some other circumstance and is not directly linked to age. A person may get acquired hemophilia from causes such as extensive liver damage or certain medications. Since these conditions normally occur in older populations it generally trends that way but is no way limited to that age set.
It is actually not possible to 'get' hemophilia. Hemophilia is passed on from the mother (the carrier) to the son, not the daughter as it is rare for a girl. A boy has two chromosomes, an X and a Y, and girl has two X's. Hemophilia is inherited through the X chromosome, so a girl can carry hemophilia, but unless she inherits hemophilia on both of her chromosomes, she can't have the disease. REGARDING YOUR QUESTION, It is actually not confirmed whether Lincoln had hemophilia, people suspected some sort of genetic disorder, there were two suspected and hemophilia was one. People didn't know very much of the disease when Abraham was president. In fact is wasn't a named disease until 1828, and then hemophiliacs often didn't live pass the age of thirteen. With not much doctors could do to stop bleeding, and considering the age of Abraham its unlikely he had hemophilia.

No, Hemophilia does not discriminate on age, race or religion. Hemophilia is a genetic disorder (with the exception of acquired hemophilia) and therefore an individual has hemophilia from the the time they are born until they die. There is one very rare form of genetic hemophilia where the individual "outgrows" the disorder. In fact, the hormonal changes that take place during puberty increase the production of the clotting proteins to a point above the 50% cut off for being considered as having hemophilia. the genetics however, remain the same.
There is no chance that the child will have hemophilia even if the spouse has hemophilia. Any girls the couple has will be carriers if the spouse has hemophilia.
