My dad had beautiful white/grey hair and ever since his passing I constantly see white/grey feathers in the air or find them right outside my door. A feather could be a cool tattoo for just that reason.
"A soulmate is an ongoing connection with another individual that the soul picks up again in various times and places over lifetimes. We are attracted to another person at a soul level not because that person is our unique complement, but because by being with that individual, we are somehow provided with an impetus to become whole ourselves." -- Edgar Cayce
