USA emigrated Romany relatives Boss, Young/ Heron

[daisydew7]

 Both sets  of my  gg Grandparents were gypsy  immigrants from England.  Sampson Boss married Susan Gray  and  Frampton Heron Young married Desibera Boss.  I  believe  Frampton arrived in the US 1855 on the USS Neptune.  I  am beginning to believe that Frampton may have remarried for whatever reason because on my great grandfather Joe Young's death certificate his parents are listed as Frampton Young and Louise Smith both born in England.  Can anyone help me out.  I'm not finding anything on a marriage between Frampton and Louise.  I don't even know who Joe youngs mother was Desibera or Louise. 
Is it possible Desibera aka Separai passed away and Frampton remarried or did Desibera change her name to  Louise Smith?  This is the information I have on Frampton's son
Joseph Young born in Ohio usa 1859 died in Chicago,  Illinois 23 March 1933 married Delilah Boss ( dtr of Sampson Boss )Michigan usa 1877
Thank you
