do they sound that bad ?

my family have known weve been stuggling to pick between 3 girls names (ivy , polly and penelope) for weeks , but everyone seems to have presumed we would go for polly , today i stated that ivy was the front runner and everyone looked at me like i was crazy and said it sounds awful with my first little girls name , heidi and ivy are they really that bad together ? ( people are saying will be confusing for the children when we call them )
