Mary (written Marey) is named in her father's WILL a number of times:
"..Son Peter paying never the less on the above estate to his Sister Marey the sum of fifty pounds proklemation money to be paid to her when she arives to the age of eighteen years. But if said my daughter should depart this life before she arives to the above age then I order.."
So by the above information, Marey is not yet 18 when this WILL is written (March 5, 1761).
" Likewise, its my will and order that my son Mathias pays forth unto the above estate granted to him unto his siter Marey the sum of one hundred pounds prock money to be paid her when she arives at the age of eighteen years."
as with info for Peter, the above information indicates that Marey is not yet 18 when this WILL is written.
"..it is my will and order that he (Martin) pays for the out of the above estate to his sister Marey the sum of one hundred pound prock money when she arives to the age of tweny years.."
by this quote, it appears that Marey will receive more money as she turns twenty
"..my son in law (Jacob Case) pay their out never the less to my daughter Marey the sum of fifty pounds prock money when she arrives to the age of eighteen years."
