The person could be charged with harboring a fugitive under 18 U.S.C. 1071 or accessory after the fact, 18 U.S.C. 3. Accessory after the fact is defined as one who, knowing that a federal crime has been committed, assists the offender "in order to hinder or prevent his apprehension."
The maximum penalty for accessory is one-half the maximum for the offenders' offense. Whether the feds would actually choose to prosecute a family member would depend on how much assistance, for how long it went on, and how much they want the offender.
Yes. 18 USC 1071 prohibits harboring or concealing a fugitive, and requires that the Government prove that a federal arrest warrant existed for the person assisted; that the persona aiding the fugitive knew of the warrant's existence; that the person harbored or concealed the fugitive (by any affirmative act of assistance, such as providing food or shelter); and that the person harbored or concealed the fugitive with the intent to avoid the fugitive's arrest.

Yes. 18 USC 4 is the federal misprision of a felony statue and provides for a penalty of up to three years in jail if you harbour or assist someone who you know has committed the federal crime. It is not enough just to know but giving food to him enables him to stay a fugitive and likely subjects you to thet statute.
