our family has a history of allergies, but we all differ in what they are/the severity. i'm one of 5, the eldest 3 don't really have allergies, more food intolerances, but my brother and i have multiple allergies/intolerances (he's got food allergies-nuts, eggs etc, i have chemical allergies-amoxil, chlorine etc). We got ours from mum (i have a different father, but neither father has allergies).
Mum has 3 siblings, she is the worst of them, therefore our branch of the family also has the worst allergies (not saying there aren't allergies floating around, there just isn't anything serious). Out of my siblings and my kids, none show any serious food allergies (yet, DS is allergic to cats and there are plenty of food intolerances).
Ours seem to go that the child with the worst allergies themselves has the children with the worst set, but there is a genetic link (most of my family ignore the fact that there are allergies in the family for themselves/their kids. i'm the only one other than mum that has had formal testing).
ETA-my kids have a double whammy, my DH also has hayfever/asthma (and i'd say a fair whack of food intolerances, but his family would never believe in something so airy fairy, DH only believes because he has been around me long enough/has seen the effects of the 'wrong' food on our DS)
