Age of Rumpus McFowl

[Larry Giver]

The latest Gemstone US #323 has William Van Horn's Scrooge story,
"Travails", which presents more details about his new character, Rumpus
McFowl.  Here in the USA, he was in the last Gladstone issue, where he
was promoted in rank from a cousin of Scrooge to his half-brother.  In this
"Travails" story, Van Horn states that Rumpus' mother was briefly married
to Fergus McDuck (page 3, panels 5-7).  It seems the marriage had a
bitter ending, as his mother never wanted him to know his father was Fergus
McDuck.
      Can Fergus fit into the McDuck family tree?  In Rosa's Life & Times of
$crooge McDuck, $crooge's mother died in episode 8, in 1897, when he was
30 years old, and his father Fergus at the end of episode 9, 5 years later, in
1902.  I can accept that a "brief marriage" of Fergus to Rumpus' mother
occurred about 1898, and lasted no more than 2 years.  Probably Scrooge's
sisters were quite upset about this marriage, and never wrote about it to
Scrooge, and after the bitter divorce, Fergus didn't want to tell Scrooge 
either.
	So I believe that Rumpus is much younger than Scrooge, about 32
years younger.  Scrooge is 85 in 1952, making Fergus about 53 at that time.
Alternatively, if the "brief marriage" was a few years before Fergus and 
Downy's
marriage, Rumpus would be about 90.  I perceive Rumpus as a unsuccessful
younger brother trying to sponge off his successful older brother.  Is this
how most readers see this?  How many stories with Rumpus has Van Horn
written by now,  many more than we've seen in the USA so far?
