My inquiry is medical. Is there anyone in the Johnson or Williams lineage that has this deformity in their line? In our family there has been two baby girls born without one hipsock formed. The first, my niece born in 1959 and the second a great niece born in 1973. Family members think this is from the Johnson side. My grandmother was a Johnson and married a Williams. I would appreciate hearing if anyone else has had this in their families at any time. Thanks, Helen
