Koronto,
This problem is widespread among all the Somali families...The dilema is :
Before men used to be better educated than women. Men were OK to marry a less educated girl..Ph.D holders even married girls that have never been to school.
Unfortunately now days, girls are more educated than men..Or atleast I should say, girls tend to attend and seek higher education more than the boys...Therefore the gap is reversed now... But unlike the guys, girls don't want to marry a guy who is less educated than them

... That is the problem...
Also, guys get very uncomfortable when they marry a girl who has more education than them...This does not help either.
There is also another factor that was always there: Bad girls always catch the best guys...Because they tend to meet more men then the self respecting, shy girl...
At the end of the day the destiny (Calaf) is what rules..
About your neices...Good men are not necessarily the ones in the Masjid..Believe me there are all sorts of men in the mosque...Don't trust a guy simply because he goes to mosque...Always someone other the family is the best person to recommend a good girl...Let the family friends do the job..
