Looking for Alphonse Joly

According to my father's great-aunt, her uncle Alphonse Joly and his wife Marie Louise Desjardins emigrated to the US.Before they left, they lived in Hawkesbury, Ontario, and had been married in 1871.I have found the baptismal record for three of their children, but the trail stops there.

If anyone knows of any descendants, please contact me.

Thanks,

Gilles
