Too Many Ed Egans

There are just too many Ed Egans. Egan is an Irish surname, the Republic of Ireland is 86.8% Catholic[1], and the Catholic Church is has been opposed to any form of birth control[2] since about 191AD (The Instructor of Children 2:10:91:2). Likewise, Edward (and hence Ed) is a common English (and Spanish, Portugese and Proto-Germanic) 'Christian' name[3]. Edward is perhaps particularly common in conjunction with the surname Egan, because it alliterates and trips off the tongue nices. Do the math(s) (note that I am stuck between cultures now, and really want to add the 's' to maths, where it belongs, but fear ridicule from my American colleagues).
