To produce the error checking and message, a serious detour must be taken, and we need to know what your OS and shell versions are.
This can produce multiple answers if $1=ann and both ann and anna are users in /etc/passwd

With bash,zsh,ksh the ~$var expansion works in eval.
Code:
#!/bin/bash
eval home=~$1
echo "$1's home directory is $home"

  • eval is evil. Make it as short and simple as possible!
  • in csh it works without eval. The whole csh is evil!
