3/4 Sibling
F/M2 = Mistress/2nd Master
F/Ma = Mom/Son
F/Fa = Mom/Daughter
F/Mx = (Grandma/Grandson)/(Aunt/Nephew)
M1/M2 = Brother
M1/Ma = Father/1st Son
M1/Fa = .75 Uncle/.75 Niece
M1/Mx = Father/2nd Son
M2/Fa = Father/Daughter
M2/Mx = (Grandpa/Grandson)/(.75 Uncle / .75 Nephew)
Ma/Fa = .75 Sibling
Ma/Mx = .75 Sibling/(.75 Uncle/.75 Nephew)
"3/4" is too confuse, so I replace it as ".75". Otherwise, I never met anyone who have 3/4 sibling. Hey Philip Fry is grandma himself! Mind blow!
